When you mix liking lusting a girl/guy so much your lushing for them.

tipsy, drunk to the point of no return.

Either sex can be a lush. It's someone who drinks a lot and enjoys drinking a lot---not necessarily an alcoholic, but someone whose drinking is noticeable. It can be used teasingly or as an insult, but even if someone teases you (or whoever), there's probably some truth in it, and it probably means you're overdoing the alcohol.

British slang term to describe something pleasing or desirable.

one who becomes intoxicated after a few drinks and flirts with everyone

Activity commonly known as drinking alcohol

To be lushed: Heavily intoxicated

If presented with an opportunity to drink shamelessly and in large quantities, and if in the mood for a drunken good time, a lush generally won’t pass up on it.
