A shit so long and large that it reaches the bottom of the toilet while still connected to your ass.
My girlfriend ate so much yesterday, that when she took a shit, it was like a monkeytail.
Monkeytail beards start at one ear and then wrap around your chin and mouth
Luke: What the heck is that thing on your face!? It looks like you just finished picking the ticks off a monkey's nuts with your teeth.
Wilger: This thing? It's my monkeytail beard!
A style of beard that resembles a monkey's tail wrapped around the face.
It starts from one ear like a chinstrap, and wraps around the chin and mouth, not connecting on the other side.
Hey, nice monkeytail beard. You look like an idiot.
