The combination of smegma, the cheesy formation of crusty jizz, piss, and pube sweat that forms primarily at the tip of your dong after days of not showering and beating off, and the fantastic chinese appetizer, the eggroll! Mainly used to describe a horrible tasting old juicy eggroll that is past it's prime, or a drunken college dudes unwashed wang.
Dude, there is no way I'm eating that 4 day old smegroll that you stuffed in the box of left over mu shu chicken!
Hey, did you hear she went home with that dude she met at the party. I guess she almost decided she wasn't gonna munch on his smegroll, but she did anyway. She told me it was like eating last nights mu shu chicken.
