NBT
NBT, or next best thing, refers to a resort to coffee, sugar or some less-satisfying form of sensory indulgence when circumstances prohibit sexual gratification.
Although sexually ravenous, as a result of hours of secretive fooling around, L and M realised that there would be no opportunity for sex.

L (rolling over): God damn, this is so frustrating!

M: I know. I'm soo randy!

L: NBT?

M: Yeah, let's get coffee.

L and M: Sigh.
