A strong alcoholic beverage invented in August of 2006 in the Bahamas. As said by the name, it's most potent ingredient is Creme de Menthe. This obviously gives the drinker an overwhelming sensation that they are drinking listerine. Best taken in very small shots after slightly inebriated.
The name was a spin-off joke on the drug crystallized methamphetamine.
- "You wanna do shots?"
~ "Yeah, let's see how many crystal menthes we can handle."
- "No way, that stuff's way too strong .. and expensive."
