(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.
