Gin.
Drank it once my Frosh year of HS on homecoming weekend.
My parents went to visit one of my sisters at Fairfield U.
I had another sister who as a Soph and she acquired some gin.
I drank way too much on the way to the dance. Made it to the gym. Walked up to the top of the stands. Sat down and rolled down to the floor. Stood up, threw up on a Senior. Walked past all the chaperones and walked 2.5 miles home.
Woke up the next morning in a pool of vomit in my bed. Parents found me there mid-afternoon.
My "punishment " was cleaning my sheets and living with the hangover.
The smell of gin 25+ years later still makes me nauseous.
