a bullshit declaration that some high school students are forced to sign by their goody goody two shoes parents that says that they won't use alcohol or drugs during prom night. Ah-ha-ha-hahahahahahahahah!
Prom Promise is an idea spawned by extreme MADD-types, Tipper Gore-types and soccer moms. If you resort to having your kids make such chicken shit pledges like that then you don't really trust them and you ain't raising them up in a good way. If you've done your max to rear them right then you have to let them loose.

Get the prom promise mug.
When you promise your prom date that you will give her "just the tip".
"How did it go last night at prom"

"It was awesome! I gave her the prom night promise but she ended up taking it right to the base!"
