anus fly-trap 

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.

Anus Fly Trap 

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!"

Anus Flytrap 

The act of holding your butt cheeks wide open in anticipation of a finger to enter the area. At this very moment the cheeks will close shut and the instigators hand will be stuck.

So Tina was showing some ass the other day so I went hand first in for it. Turns out she was pulling an anus flytrap on me, again.
