noun or verb (used with object)
When riding on the back of my motorcycle and visor of the driver's helmet is open, the person riding on back farts into their cupped hand and quickly (to preserve integrity of fart scent) delivers said fart into the helmet and promptly slams the visor shut. Extra points if your efforts result in a crash, adding injury to idiocy.
Dude, I already felt gay enough with Hector on the back of my bike, then on top of that he gave me smelmet while we were going like 70 on the 405. Fuck Hector.
