Any member of one's chosen gender that makes it into that piece of furniture ordinarily used for sleeping (or, alternately BUMPIN' AND LOVIN' IN THE BED). A bed-buddy's purpose is usually sexual in nature, although s/he may also be a cuddle provider.

Often abbreviated as "BB."
She shook her head when asked if she and Alain were dating; he was simply a bed-buddy, and nothing more.

Rachel thought Shannon and Lucas would be bed-buddies because ice-blue eyes and brown hair are irresistable.

It is sex with someone you know for a long time. Not an emotional "love" connection, just someone you care about as a friend only and it is just sex for mutual pleasure.
If you can't fuck your friends than who can you fuck a total stranger you know nothing about? Better and safer to have a bed buddy.

It is sex with a friend whom you've known and care about but not as emotional, love interest relationship. Someone that can maintain the separation of sex and being in love.

As long as both partners understand the boundaries it can provide a lifetime of fond positive memories.
