Things you didn't notice on The Wire until multiple watches

He said it referring to gay sex/violating inmates in prison.

When they pressed him about liking to touch little boys, he was copping pleas about being into women/p*ssy.
Chris said, but aint no p*ssy in (jail)

Thats when he says the line you mentioned.

Chris got triggered, likely having been violated in prison by a predator.

Chris got triggered because he was molested himself as a child.

Stepdad says that line and Chris says "I do" and beats him. I took that as him understanding what he means when he says "a man's gotta bust a nut, y'know?" is he knows what a child abuser looks like because suffered at the hands of one.

It's why when Michael pointed out the stepdad to Chris/snoop, Snoop was questioning why he wanted him dead but Chris could look at Michael and understand what was going on.

Also it confirms that the stepdad is willing to fukk w/e is around, so all that "i like p*ssy" shyt is out the window when he said he fukked dudes in jail.
