Shit-nel 

A young girl, sometimes of unconsentable age, who may have sexual affiliations with the opposite sex, but only if their age is much greater than their own. Shit-nel's are known greatly for their ability to piss off siblings, parents, and other close family members. On some occasions, Shit-nel's cause plants to die when the Shit-nel comes within five to 10 feet from said plant.

"Look how pissed off everyone is! Stop being a Shit-nel!"

"All my plants are dead!! Must be that Shit-nel coming around again."
