that guy at the party who is ALWAYS THERE, you dont really notice him during the party, noone really knows him, but when you look pictures the morning after, he will be there, in the background, smiling with a beer, most likely giving the thumbs up sign.
"dude whos that guy behind you with the thumbs up in this picture?"
"I dont know man, I thought he came with you!"
"HES THE YEAH GUY"
