A "prison pussy" is a configuration of facial hair which surrounds a man's mouth (also known as a "goatee"). This ironic term is intended to insult a man who thinks his well-trimmed facial hair makes him look tough. The overt implication of the term is that men in prison would use his mouth like a vagina. This insult is especially powerful when it is spoken by a woman.
Do you know that guy John? He's a white guy, about 6 feet tall, with a prison pussy.

Get the prison pussy mug.
The mouth of a male prison inmate who either willingly or under duress sucks dick while in prison. Sometimes used more narrowly to refer to such inmates who wear goatees or mustaches.

The term serves as an analogy to the vagina's role as receptacle for the penis, with male facial hair viewed as analogous to vaginal pubic hair
