Whore water

The water bottles you give to hookups when they come over. Not the good bottles. They may be off-brand, partially used, or refilled ones... Also applies to alcohol and other beverages.

Ayy that girl is coming over, can I give her some whore water? Gotta hydrate, but can't waste the good stuff on Kayla
