Mnemonic device for "Black Out Make Out". As a verb refers to when someone is so intoxicated that they makeout with someone they ordinarily would not. When this person realizes they are in fact making out, they need to stop immediately and leave the premises. When used as a noun it refers a person with whom someone would bomo.

Bomo's are a good thing. People who are bomoed should be flattered.
Verb: Q: "Did you bomo last night?"
A: "I don't remember"

Noun: Q: "Do you like him?"
A: "No, he's just a bomo."
