A unit of currency. When a woman does something exceptionally nice for a romantic partner, she earns a triplelingus--three solid sessions of cunnilingus.
Used to descirbe something/someone epicly amazing... Like me! Do not use this on someone/something who is obviously not a triplekickassrainbow. Usually used to describe cookie monster cupcakes.
Pix: Kyra kyr, your a triplekickassrainbow!
Me: awww thanks Pix :D
