When you can't actually argue with someone based on facts so you just make fun of them instead.
Trey Parker and Matt Stone are too stupid to actually argue global warming based on science, so they decided to manbearpig Al Gore.

From an episode of South Park featuring Al Gore. In the episode Gore is depicted as a paranoid guy who believes in a non-existent monster--"Manbearpig"--that is part man, part bear, and part pig. He believes the Manbearpig is a great threat.

South Park's creators, Trey Parker and Matt Stone, don't believe in global warming and the episode "Manbearpig" is their way of saying that when Al Gore talks about the dangers of global warming he is getting all worked up over something that doesn't even exist.
"The South Park guys think that global warming is a myth just like the Manbearpig, even though there's tons of evidence that it's happening, and they make fun of Gore for worrying about it."

A disgusting, foul, ugly ass chick who you just cannot stand! Usually resembling a man in the face, a bear in the body, and a pig in personality, this foul creature lurks in the back of your study hall, the middle of the locker room, and at the front of the lunch line! Give her a cookie and she'll love you forever, give her a cock, and she'll suck it, fuck it, then put a bun and mustard on it and treat it as a hot dog.
"dude, did you see that new man bear pig that just transferred from Florida?"

"damn dude... that creature sure is one ugly man bear pig... how long til she eats some1?"

Another name for a beast known to live in a basement on Downer Street in Milwuakee, WI. This alleged creature is known to be quite the anti-social creature. He usually will not convene in places consisting of more than three or four other humans. Known to have a ravenous appetite consisting of McDonalds and Burger King. Also, the creature is not know to be smooth in interactions with other people. Most interpersonal reactions with this creature end up with one or both parties being embarrassed. Many speculate that Manbearpigs utterly horrifying appearance resulted from his mother getting pregnant via the water wheel (see definition) and then doing copious amounts of heroin while pregnant. If you see Manbearpig, avoid at all costs. He is known to be a compulsive liar.
I tried to talk Manbearpig into going to a party, but because a large number of people were there, he declined, stating that he would rather masturbate alone all night.

the single biggest threat to our planet. something out there which threatens our very existence and may be the end to the human race as we know it. i'm talking of course, about...

manbearpig is Al Gore's way of getting friends because he doesn't have any.
