This is when a so called "retard" cups his own shit and piss, and thinks by eating it he will unlease the reatard juice.

He doesnt know that retard juice actually isnt a real thing.
GUY 1: Did you see the retard yesterday
GUY 2: Yes i cant believe he cups his own shit and piss, that cup must smell.
GUY 3: I think its retard juice
