Another name for a happy ending, full release, or hand job. Named for actor Kevin Costner due to his hotel happy ending scandal.

Costner is probably one of the best people you’ll ever meet. He’s very funny and caring. He will make you laugh like everyday and his expressions are spot on. He even wants to be your friend even when you say that you can’t be friends. He can also speak French, and will continue to speak French to you even when only respond in English. He won’t let you do knee spins but that’s fine because he cares. He also has an addiction to blue Powerade and likes to waste drinking glasses but his personality makes up for it. He’s the best stepdad/actual dad/best friend/cat person ever.
