I almost don't wanna say these two, especailly the second one, since it's so easy to be accused of being gay these days, and since the gay life is so much more of a normal thing than it was in the 80's.
"Yall got something for the head?". This was something you'd ask two or more brothers, if they wanted a ride to the liquor store, or if they wanted to ride with you to a party. It was a way of telling them they had to at least pitch in for the alchohol, if they couldn't give you gas money.
"Butt Boys". This is a real tough one to understand today, however it simply meant your closest and earliest childhood buddy, especially from the hood...almost as if yall known each other since wearing diapers. This term was used a lot in the 80's in some of the roughest hoods.
