Poomba-ing is when you hogtie your partner, then while having anal sex you shove bugs* in their mouth, then jam an apple in and sing 'if you're achin', oink oink, for some bacon, oink oink' to completion, and finish with the phrase "slimy, yet satisfying".

*It's particularly important to use live grubs where possible.
I had the live grubs and apple, and she was already tied up, so I Poombad her.

I think I might try Poomba-ing with my cousin this weekend.
