You start by going number 2, diarrhea into a bowl.
Then you grab a friends or boyfriends penis by surprise (while sleeping or not paying attention) and twist/turn it in your bowl filled with excrement.
That's when you yell you've been Turnbowl'ed !!! Bitch!!!
Originated from Mexico.
Originally " Vuelta Peto" Which meant turned penis or penis Honker/Turned Honker or penis circles.
Was renamed by a white male.
I pulled a "Turnbowl" last night on a Reader while he was drunk.
Reader's response: someone must have Turnbowl'ed me last night while i was hammered.
I wish i could " Turnbowl " my teacher, he is suck a prick.
If i am tortured i wish i am never "Turnbowl'ed"
If i see you talking to my girlfriend again, I am gonna give you a "Turnbowl"
