ride the blue wave
to go out drinking without much money, or to be with friends who are drinking when you cannot be drinking. The term comes from when funds are low and one must theoretically resort to other resources of alcohol (such as mouthwash) to get a buzz. Note this term does not imply drinking said mouthwash.
1: Would you like to go out drinkin' tonight?
2: No, I've no money. I'd be a fifth wheel.
1: Don't matter. Just ride the blue wave with us anyway, man.
