Combination of WTF and FB. Literally, a "what-the-fuck-buddy". Someone you like, and have sex with, but can't tell whether or not you're in a relationship or not.
J: "I haven't seen my WTFB in almost a week."
M: "... I just hung out with him yesterday."
J: "He gets along with my friends better than I do! When do I get to have sex with him again?"
