pro-bonor 

When a girl fucks you for free, because she likes to give it away. Like free legal representation when the attorney approves the cause.

"Dude, I can't believe I boned her. She's never been down before."

"Sounds like she's down for a pro-bonor."

"John, you going to help at the charity auction?"

"Is Shelly going to be there?"

"Yeah."

"I could help out on a pro-boner basis."
