Whether it's calling a reporter a scumbag, or dropping F-bombs on Twitter while labelling a combative fan as goofy, an idiot, dick or douche, UFC president Dana White says what he thinks.

So when White tweeted in November 2009 that welterweight Karo (The Heat) Parisyan had screwed (or some such word) the UFC for the last time -- "He will not be fighting saturday or ever again in the UFC!!" -- it seemed definitive.

But come Saturday, Parisyan will be in the cage for UFC 123 in suburban Detroit when he takes on Dennis Hallman.

"I never thought the door was closed," Parisyan told The Canadian Press. "I knew that I would fight again, I just knew it.

"I know Dana White. I know how he thinks, I know how he works. And when somebody says something like that, I know that in the heat of the moment he got pissed and he just said that. I knew I would eventually make my way back to the UFC because I didn't kill nobody.

"Dana's got a heart, man. He has a heart. And he does care about his fighters. He does care about people. So what (if) he makes more money than fighters and he gives them a little bit and he keeps a lot for himself. Yeah, he's a businessman. He's the one that put the whole empire together. So he does deserve it.

"Sure, if you need money, you talk to him, you tell him. Dana never says no that much, unless it's something outrageous. He'll work with you."

Parisyan (26-5 with one no contest) remembers some years ago when Xyience, which makes supplements and energy drinks was an exclusive UFC sponsor and a rival company wanted to sign up him for $1,000 a month.

Parisyan went to White to say he needed the money.

"He said 'You know what, kid? Sorry.' He gave me $15,000. He just sent me a cheque. He said 'Here I'll just send you this money, just keep it between me and you."'

Parisyan said White also allowed him to wear an Affliction shirt while the UFC and the clothing company were sniping at each other.

"He even let me wear that (shirt) because he didn't want to take any money out of my pocket. He's a very nice guy, when it comes down to it. But if you screw with him, he'll screw you back even two times worse. So you have to be loyal and nice."

What is White's current take on the newly restored Parisyan? "Lets hope he does the rite thing," the UFC boss said via text.

Parisyan, who has fought 12 times in the UFC, has disappointed in the past.

He dropped out of UFC 88 the week of the fight in September 2008, citing citing sciatic nerve problems.

"Anxiety led to that going even more crazy," said Parisyan, who also suffers from severe panic attacks. "It was just whole combination of things, man.

"I've never been 100 per cent walking in the cage. The best I've been was maybe 70 per cent and I wasn't even 10 per cent for that (UFC 88) fight."

At UFC 94 in January 2009, he beat South Korean Dong Hyun (Stun Gun) Kim, only to fail a drug test.

The 170-pounder tested positive for hydrocodone, hydromorphone and oxymorphone. All three are painkillers which he said were prescribed for his hamstring and sciatic nerve.

He was banned for nine months and fined US$32,000 -- 40 per cent of his purse. His split decision win over Kim was also declared a no decision.

And when he served out his suspension, he pulled out of UFC 106 the day before the weigh-in in November 2009 with what White called "a laundry list of excuses."

That prompted White's Twitter rant.

Parisyan has denied having a problem with painkillers, saying everyone has taken such a pill in the past.

"That doesn't mean you're a pain pill addict."

Parisyan is still upset he was so heavily penalized for a narcotic he says allowed him to dull the pain and sleep, rather than cheat while fighting.

Athletic commissions argue, however, that anything that dulls pain can actually lead to injury in fights.

He has fought just once since the positive drug test some 22 months ago. That was a win over Ben Mortimer in Sydney, Australia, in July on an Impact FC card.

Parisyan said he went Down Under to prove that he was able to fight anywhere, despite a history of panic attacks triggered by small hotel rooms and being by himself.

Parisyan said he spoke to White several months before the Australian fight.

"I told him 'Listen I'm going halfway round the world to fight,"' he said. "He said, 'OK get one fight under your belt and we'll go on from there."'

Parisyan, who was once looking at a UFC title shot only to be denied by injury, is back in the UFC but he has a long comeback road ahead of him.

Part of his weekend paycheque will go to the Nevada State Athletic Commission to pay off his doping fine.

The 28-year-old from North Hollywood, Calif., said not being able to fight played havoc with his finances.

"My overheads were just through the fricking roof. How am I going to survive? That put me into debt, a lot of debt, more debt than I've made in the last two years fighting. That's the bullshit part of this sport, that if you don't fight, you don't make any money."

Asked what he did to survive, he replied: "I did what I had to. I didn't rob a bank or anything. Loans, and my credit cards and etc. and personal stuff that I had to do to survive and be able to take care of me and my family until I was able to fight.

"It dug me into a hole from where I'm trying to crawl out now. It's really bad, it's really unfortunate situation. We're trying to get that out of the way. It's going to take me a while."

Still there is a trace of bitterness as Parisyan says at the end of the day "everything is about money."

"So that's what I'm shooting for. (Keep) my eye on the prize, fight and make money, pay off my debts and live my life. I don't give a shit about anything else or anybody else. No one ever gave a shit about me when I fell."

As for Saturday, he says he just wants to put on a good performance "and have people say that was a good fight."
