Toilet About Face
The uncommon phenomena (predominantly a male occurrence) of standing to go piss but then realizing you have to shit. This occurrence is even more rare when one is seated to shit but upon completion a realization is made that a standing piss is necessary.
"Bro, whut took u soo long?"
"Yo, I thought I just needed to piss but it turned into a toilet about face."
