So the past tense of "take a turd" is "went tard". If you are doing it for the second time you "take a returd". If you are referring to the second event in the past tense then you "went retard"
a "shat" is what one takes after too much drinking and dancing. it's just like, "damn, that was one nasty shat." you don't want to take a shat when in a stall around others, or do you?
