a certian individual that lacks key social skills and at times can sound mentally retarted. ussually finds his/her jokes much funnier then anybody else and will laugh loudly at them. has a false sense of himself/herself and will often think they were once much cooler then there are now. not very good at anything but still finds a way to enjoy himself/herself. similiar to a douche, loser, bitch.
did you see what john did today?!
yea, hes just a douche bag.
