BYOM

slang An initialism of "bring your own marijuana," a play on "BYOB" ("bring your own beer"), which is typically used of a place or event that does not serve beer but permits patrons to bring it with them. After the recent legalization of recreational marijuana, a number of BYOM bars and restaurants began cropping up all over the state. Why does it reek of weed in here? Is this one of those BYOM places? A: "Some of my friends want to go a BYOM place tonight." B: "Are you nuts? Do you really think Mom and Dad won't notice we're stoned when we get home?"
