When you lightly push your anus to see if what is coming is just a fart but then you realize it's actually a poop and the tip of the turd begins to come out just like a turtle sticks its head out of its shell to check its surroundings.
Emma: Damn I thought I just had to fart but when I was turtle heading I stained my underwear.
Emily: I told you not to push that hard, now we have to buy you new undies!

The act of pinching off the tip of a loaf after it has been coming out of your asshole before you reached the bathroom. Most of the time resulting in a skid mark in your drawers.
Hey, can you pull over at the next stop? I'm guillotining a turtle head over here. (spoken from the passenger seat during a long drive)

Extremely small penis caused by excessive fat in the pubic/groin area. Penis can shrink back into the scrotum and totally disappear, like a turtle's head.
Since I've put on all this weight I've developed a turtle's head dick! Every time I look down at it the head sucks back into my scotum. Poof! Out of sight!

another way of saying "skid marks". "Turtle head poking out" often refereed to as Needing to take a dump so bad that a lil pokes out. "Graffiti" represents the skid marks in one underwear via "turtle head".
