A dirty alex and Gracie is when you put crackers in a circle in the middle of the room, dance on it, and then grab a jug of your semen, stick a bouncy ball inside the jug full of semen, when all covered you need to hit every cracker or else you lose and have to use the other persons semen like mouthwash
Yo, dude. I just did a dirty alex & Gracie last night and even recorded it
When a group of friends have a party and someone falls asleep, they place grapes into the sleeping friends ass and wait for them to rocket the grapes out when they fart. A dirty grace is when the grapes are flying.
“Mark fell asleep so we made him preform a Dirty grace. He won’t be falling asleep around us again”
