when someone,usually a male, clamps there ass cheeks on a persons nose(usually alseep) and then farts. a very horrible experience.

When you put down a layer of toilet paper or a paper towel in the toilet bowl to prevent splash back from taking place when your planning on dropping some heavy freight. The weight of the freight causes the paper to fully envelope it and cause it to be consumed by the paper.
After I took a heavy dump, I tried to take a look at the damage, but the anus fly-trap had already consumed the evidence.

When somebody is taking a nap outdoors naked, anus exposed in a relaxed (slightly open) state then a fly comes along and lands in their anus, causing it to reflexively close. Trapping the fly inside.
"I couldn't figure out why my butt itched so much after camping yesterday , after a bit of finger digging I found out that I am part anus fly trap!"
