(verb – present participle) The act of experiencing the summit of a crusty turd protruding from your sphincter (a turtle head
); to really need a crap
Onlooker: "Why are you walking so strangely?"
Protagonist: "I'm turtle-heading, if I don't find a toilet soon I'm going to purge all over my pants."
Turtle heading is when you need to take a shit and it is starting to peer out of your ass. Like a turtle coming out of his shell.
"Hey bro let's move!"
"Hold on a sec I need to take a dump."
"Can't you just hold it?"
"Naw man I'm turtle heading!"
Refraining from such act as "pooing" when your turd comes out a little and then goes back in!
Right now im Turtle heading.
Dam i need the crapper, i'm turtle heading!
