Yahweezy, or "Yahweezy BBY!" is a term used to describe a teenage child who wants to fit in with a crowd of older kids, but simply looks pathetic. The "Yahweezy's" often have completely stupid inside jokes and wear all-girls-school shorts that increase the likelihood of people viewing that as entirely homosexual. Their mix of a ghetto "in yo face attitude" and the hardcore elements make their persona very lame. Lame is the perfect definition for this word.
