look up any word, like the eiffel tower:
When a married man goes out clubbing or bar hopping with friends and puts his wedding ring on his key chain so he can pretend to be single and have fun. Now this doesn't mean that he is going to cheat on his wife, it just means that it's easier to have fun in a club if you're not dancing by yourself 'cause every woman there can see that you're married.
Guy 1 "Dude, where's your wedding ring?"

Guy 2 " I'm Key Chaining tonight"
