used to describe:

1)any person who, regardless of reasoning, just can't pull the right moves to be with the 'in' crowd

2) any failed attempt at a cool stunt or complex pick-up line

3) an overly dressed or tacky person
1) After witnessing the new kids outdated dance moves, the clicke of 'cool' kids declared him wack and moved on to the next wannabe.

2) As the kid dusted himself off after failing at a double beer chug, one of the girls muttered to her friend" wow, that boy is wack!"

3)As the jeri-curled, headband wearing, oversized pendant bearing thirty year old made his way towards the party from his rusty el camino sittin on 20's, about fifteen people asked their friends 'who's this wack mo-fo?'
