A state of being that is unlike any high. The feeling one gets after taking a bite off a nerd rope, a sprinkle of pop rocks, a swig of Diet Dr. Pepper Cherry, and farting (sequentially). Vanilla Coke can be substituted if Diet Dr. Pepper Cherry is not available, but your shrimsiness will be severely tainted.
Dude-bro, I was straight shrimsy last night. Shrimsing all up in that party.
