The state a guys penis is in after being squirted with the juice of a citrus fruit. This sometimes happens purposely to eliminate and annoying erection.
-Dude, why are you crying?
-My erection has lasted about 3 hours, so my only choice was to make it Citric Flaccid with this lemon I found.
-That must have stung pretty bad.
-Ya, but at least my erection is gone.
