When a person feels they have let out the longest log turd of all time, only to look in the toilet and see a rabbit pellet looking shit. The feeling is most disappointing for twitter shitters everywhere.
"I was going to tweet about this giant shit I took, but alas it was a phantom turd snake."
A turdonkey is what you call a fat chick that sits in the middle of a ski run and blocks everyone else from going downthe mountain. Combines a "turkey" which refers to a person who takes up the middle of a ski run and a "donkey" which refers to a fat, ugly chick.
I almost skied right into that dumbass turdonkey today as I skied down a run. Would of been like hitting an elk with your truck.
