sour mash 

(v) when a man cannot get an erection, but proceeds with the act of coitis anyways

etymology - the limp penis is mashed against the vagina resulting in a poor (or sour) sexual experience; the term also alludes to whiskey dick, as sour mash is the name for a process in the distilling industry that uses material from an older batch of mash to start fermentation in the batch currently being made

After consuming a fifth of Jack Daniels, and suffering from whiskey dick, Larry sour mashed Lindsay anyways.

Sour Mash 

When the semen used from a previous jerk session is used as the lube for following session. Derived from the definition used in the whiskey making process.

So I wanted to rub it again after I was finished but I ran out of lube. Had to use a sour mash.
