When two people sit in two bathroom stalls and neither will shit because they don't want the other person to hear them shitting.
I'm so glad we have one bathroom with two stalls for 100 people at this fucking place. I've needed to take a crap for 20 minutes but Doug and Troy are in there in a Mexican shit standoff.

Someone who spends the majority of their workday clogging up the toilet and consistently smells like ass. Someone who who shits every hour on the hour, has no intestine, just a shit tube running from their throat to their ass, has been known to shit watermelons and small marsupials.

The family campfire was going great until uncle Frank came out the trailer showing off his shit-tucky mushroom.
My girlfriend has a shit-tucky mushroom.
It was within the hallowed walls of the gym locker room that observed the performance of the shit-tucky mushroom. I would never have believed it had I not seen it myself.
