Jack+Jill
A Jack and Jill party is when a bunch of people show off their private parts for fun. No touching, just looking. It's like a show and it's super embarrassing.
My friends had a Jack and Jill party and my mom came in and saw everything.
My brother had a Jack and Jill party and got caught by his teacher.
My cousin had a Jack and Jill party and got kicked out of the house.
