The art of rummaging around in a ones nostril for a tasty treat. A complete lack of shame and decorum means that this can be done at any time and in any place regardless of who might be watching.
akin to how a pig truffles in the forest for the famously hard to find truffle mushroom, "ass-truffling" is the act of snorfling around in the drawers of your lover looking fordingle berry gifts to sniff and chew.
Your average ass-truffler will make grunting noises followed by squeals of delight when treasures are unearthed.
*ew ew ew* *get away get away get away* help meeee, this guy I brought home from the bar is ass-truffling meeeeeeeeee!!!!
Bitches be Trifilin. Paige quickly got my pants off last night, then proceeded to kiss my inner-thigh for 20 minutes before calling it quits and leaving me with blue balls.
