Jail purse- The anus of a male or the vagina/anus of a female. Commonly used for storage of small items such as keys (to handcuffs) or small baggies containing drugs.
Cop1- Yo man, we just arrested this one girl. After we brought her down to jail they found 12 baloons of heroin that we didnt find when we searched her.

Cop2- Lemme guess, she was hiding it in her Jail purse?

Cop1- Yup, even had a handcuff key up there.
