n. The act of allowing one's lips and cheeks to vibrate while pressed firmly between another's ass cheeks and exhaling forcefully.
It usually elicits many giggles and protests from the victim to stop.
Similar to a zerbit, this is done with your face is pressed in between the ass-cheeks of another person.
You then exhale out of your lips forcefully, similar to the way you would blow on a musical trumpet or do the "motorboat" to a pair of large breasts.
The resulting sound is similar to the sound of one passing gas.
He had his face between my ass cheeks and gave me a farts nuggen!
I thought I was farting on his face when he gave me that farts nuggen!
