Trishta is how you identify someone who has experienced the insertion of one man's sack in their mouth. Used a practical joke or prank, when performed on someone who is asleep, or as a sexual act.
At the frat house last night, when Tim was wasted an down on the floor, he got teabagged by, like, ten guys! Wow, that guy was a Trishta last night!

Me and Jen were teabagging last night when her mom walked in. Awkward. Jen's parents only call her Trishta now.
