A douchebanger is a girl who
repeatedly has sex or hooks up with complete
douchebags. She may be slightly aware or completely in denial. She does it
on a regular basis, and has not been well exposed to other types of men... normal guys who have manners, normal taste in clothing, and know how to treat a lady
"Wow she's such a douchebanger, I can't believe she's
going home with that douche-sack." Girls who usually have low sel-esteem or think they know what is "cool"
sleep with douchebags. Therefore, she is a douchebanger.
