A hair grooming technique used by adolescent males who take pride in looking like complete douchebags, or "tools." Style consists of long bangs and a shaved back of the head. In the most unfortunate cases, hair on top of the head is worn gelled and sticking up.
Note: may also be accentuated with bad yellow highlights, and serves the purpose of turning women off those sporting these dreadful locks.
jessie: hey, caitlin! Your boyfriend's tool cut is pretty heinous.
caitlin: i know! it sort of makes my eyes bleed when i look at him.
jessie: that haircut has "i'm about to be single" written all over it.
caitlin: pour me another shot?
