An extremly awful-tasting knock-off of the popular drink Mountain Dew. Made by Coke (see evil), Vault is what vampires drink when they can't find any human blood. Vault is commonly confused with toxic waste, and can be found in septic tanks nationwide.
You: Dude, that's not Dew!
"Friend": Oh yeah, it's this new stuff callled Vault that's supposed to taste better. Plus, it's cheaper!
You: I don't know, dude...
"Friend": Trust me, it'll be fine.
You: Alright...
"Friend": Sluurpp... (has a heart attack and a stroke at the same time and dies)
You: That'll show him! DO THE DEW!!!
