The best friend that, no matter what state you are in, always gets you pumped up to turn up.

Supplementation Partner 

A sexual partner outside of your primary relationship in which the partner "supplements" what your main relationship is lacking in. The term is used as a less crass version of "fuck buddies" or "friends with benefits."

"My husband won't go down on me, but my supplementation partner sure does."
