Y.B.F.S.

Younger Brother Fat Syndrome. This syndrome affects younger brothers, especially youngest brothers in a family with all boy siblings, that are significantly heavier than their older brothers.

Did you see Johnny's younger brother waddling out of McDonald's? He's Twice the size of Johnny! What a case of Y.B.F.S.

Did you see Andrew's brother with YBFS fall down? He's so heavy he couldn't even get back up! He just rolled on his back like a turtle until some fire fighters came and helped to lift him back up!

G.B.F.F.

Gay Best Friend Forever... typically used by a straight person when referring to someone with whom they have a close simpatico. They click on several levels and have a lot of fun together, sharing of advice, etc. But there is no romantic interest. Can be used across and within genders.

After all the advice Ty's given one of his straight co-workers... Tom now refers to Ty as his G.B.F.F.

Diana says Michael is her G.B.F.F. at work, because they totally have the same taste in food and guys.
