Ass trufflle occurs when two straight males get bored and proceed to shove eachothers' noses in eachothers' asses pretending to look for the elusive ass truffle....not to be mistaken for the homosexual version called tossing the salad.
friend 1: Man I'm bored.

friend 2: Me too

friend 1: why don't we ass truffle eachother?

friend 2: Isn't that gay?

friend 1: only if you toss my salad.

Get the Ass Truffle mug.
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 for dingle berry gifts to sniff and chew.

Your average ass-truffler will make grunting noises followed by squeals of delight when treasures are unearthed.
