1. A washing or soaking (as in water from a public bathroom sink) of all or part of a man's private parts.
I caught Joe bird bathing his balls in the sink again at work. Thankfully, I refrained making eye contact with him as he had his pants around his ankles.
when someone playing battlefield 2, just runs around in a base not killing anyone repeatedly dying
Marc stop bird bathing in the base and do something for our team!!
