When a female is filling in/drawing on her eyebrows, and after both are finished, she comes to the realization that they aren't quite symmetrical; therefore resulting in having to undergo 'eyebrow repair' without harming adjacent makeup.
female #1: "shit! I was drawing my eyebrows on, and they look totally different..."
female #2: "thats okay girl, just do some eyebrow repair!"
Origin of this term comes from a girl who cannot get her eyebrows right, and goes back and forth trying until both eyebrows are too thin or gone altogether.
Term also applies to other types of girl stuff, like haircuts, makeup, and even things she is doing outside her own stuff.
Rosey: Hold still, I can't get your neck right if you keep moving!
Jer: I have been holding still for an hour woman! Stop eyebrowing with the clippers and fix my damn hair!
Rosey: I'm not an eyebrower! You just won't hold still!!
