Help with a word

[Madame Adequate]

Shoving your face between a woman's tits and blowing and moving your face side to side rapidly is known as motorboating.

What do you call it when you perform the same procedure with her buttocks?

[Mirage]

Rear motorboating

[Jinx]

Rimming?

Pike, you freaky girl.

[Shorty]

We call that "inappropriate."

[Pike]

Pike, you freaky girl.

I'll have you know I have absolutely nothing to do with this because we've hardly touched anything outside of videogames since he got here and I'm not exaggerating

[Madame Adequate]

She's really not, and making a noise between her buttocks would not be the same as rimming.

Sarah, you are the actual worst.

[Shiny]

I thought that was twerking, but it's probably called smearing.
