Well...a lot of blacks go to prison. And in there...well...it makes sense.
Look at the number of black men walking around with their pants below their butt hole. This is a practice used by black males in prison to let other inmates know they are willing to be ass-fucked. This is common knowledge among prisoners.
Oh, that's too funny...you are funny. Where did you learn this, when you were in prison? Too funny. Common knowledge, really? And you know this because you've been in prison or you hang out with a lot of cons? You're hilarious.
Because the only way to find out what happens in prison is to be there, right?
Idiot.
No dearie, I'm using logic and reasoning. Two glaring points: if a convict tells you a story about prison life, one as ludicrous as this one, the chances of it being true are extremely small. So I made a sarcast remark, which obviously went over your head.
The second point is that prison officials would not allow the men to walk around with their pants so low. It is not done. They have rules about how the prisoners are allowed to dress. The whole story is foolish and ludicrous. So I make fun of the person who was telling it because he is so gullible, or so wanting to believe such a story. That was over your head too.
