Jailtalk 

The swoon of bullshit that comes out of a newly incarsarated person's vocabulary. Such as poetry.

Girl, Don't listen to that jailtalk he will be hittin on hoes the first day he comes home. He ain't in love with you. He just needs someone to talk shit to.

Jail Talk 

When a nigga is in a jail and got no bitches in there but you to call you. He calls you and makes believe you’re the one and he will do good when he’s out.

“Baby girl he don’t love you, it’s all jail talk.”
