ugly stare
the resault of a very very bad attempt to check out a girl/guy,who ends up noticing you staring at them. Upon eye contact you find out this person is not nearly as good looking as you thought(example: butter face, good from far, far from good). The end resault is the continuous stare down from him/her until you are lucky enough to escape their site line.
Ben got the worst ugly stare from that cashier at the store.
