look up any word, like fap:
This is urban slang. You may have heard of "dude" and "man" and "bro" and most recently, you will hear kids saying them all together now. "Hey dude man bro!"

Well the kids are now saying "Dude man bear pig" as a greeting. This was adopted from the episode of the television show "South-Park" where Al Gore hunts a "man-bear-pig"

So this is a greeting. I believe it originated in the very trendy "Dirty Den" of Meriden CT.
Mike: Hey dude man bear pig, whats going on?
Johnny: Eh, not too much, boutta sop some tang tonight
Mike: Nice breh, give the ol' in out for me.
