a term coined for gay marriage in south park county colorado
Governor: I believe that I might have come up with a compromise to this whole problem that will make everyone happy! People in the gay community want the same rights as married couples, but dissenters don't want the word 'marriage' corrupted. So how about we let gay people get married, but call it something else? You homosexuals will have all the exact same rights as married couples, but instead of referring to you as 'married,' you can be “butt buddies”. Instead of being 'man and wife,' you'll be “butt buddies”. You won't be 'betrothed,' you'll be “butt buddies”. Get it? Instead of a 'bride and groom,' you'd be “butt buddies”.

Term used for two partners that regularly engage in anal sex, but do not share the usual emotional attachment of a standard boyfriend-boyfriend relationship.

Often used to describe two people who use each other solely for sexual gratification and nothing else. Usually this is a sexual relationship that still allows for each partner to seek sexual and emotional relationships with other people (hence, no attachments) but can rely on each other for a quickie or a booty call .
1) Whoa, I just saw Joe and Jim butt fucking in the locker room! Are they Dating?

Oh, nah, they're just butt buddies.
