Second thought: I spent nearly 25 years working as a technology IT support person in public schools.

THIS IS EXACTLY THE FACE every time I told a female middle school & HS students. Usually accompanied by stamping feet and clenched fists.

By the end of my tenure, this behavior was moving down into the K-6 group.

The males usually mumbled something under their breath. Almost certainly an F this and an F that was part of their diatribe and stomping off.

"I am not a child!"

Skank works better, though.
