prom promise 

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.

Prom Night Promise 

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!"

Prom Ise 

A phrase sneaky assholes use to cheat themselves out of promises, however, they haven't read this and don't realise they must keep their 'Prom Ise'.

Person 1: I prom ise to do this thing as long as you do this other thing. *Person 2 does the other thing then asks for the first person to follow up on their side*Person 1: No.
