Philly slang for a bloody or fat lip. The term refers to the similarity in color of ones lips after eating a cherry water ice, to that of a bloody or fat/red lip after a fight.
Watch what you say out your mouth because I might go in it. I'll give a nigga a cherry water ice, fast.

CSW or Cherry Soap Water When you have a liking in someone, and want them to slip in your DMs. Or you may think someone likes you, and you want them to like you back.
