The act of receiving a blowjob from a girl in the shower while the warm water hits the back of your head. Folding your hands behind your head in triumph is not required, but strongly encouraged.
A triumphant knee banger is when you push a girl's head towards your nether regions in hopes of getting a blowie, but you accidentally slam her head against your knee. She then vomits and grosses you out, the toxic waste falls on your crotch, staining your pants with vomit. After a while you realise that it doesn't feel so bad and cum. Hence the name.
A cruel and unusual sexual manuver which involves: a middle-aged paraplegic mongoloid (perferably a woman), honey, and one of your best-friends. This is where the second half of it comes, in other words, this is where you "Double-team".
Cody, do you rememberthat one time, long ago in our youth, when we performed the long sought after "The Triumphant Beehive"? Wow, what a messy, messy day.
