1 definition by je suis, tu n'est pas
a person who one fucks on the side when not involved in a serious relationship. NOT to be confused with a boyfriend or girfriend, to whom (gasp!) commitment would be involved.
My friend with benefits constantly tells me about how he is still in love with his ex-girlfriend...what a sonofabitch.
