A night in which friends gather together and get so crunk that after the partying, all they can physically do is sit on the couch like a grandma and rock back and forth.
Mike, Jordan, Zach, Robert, and Matt had a grandma night last night with a bottle of Vladimir. Zach passed out first. He was such a grandma.
