hairtosser
A girl or woman who is continually flipping her hair without touching it by tossing her head, often using the motion to catch a quick, surreptitious glimpse around her surroundings and/or to see who, if anyone, is looking at her, and/or to garner attention. (See "Headshaker".)
"You'd think those hairtosser gals would develop neck pains after repeating that motion sixteen hours a day."
