A nesbit is a boy who spends too much time with his girlfriend. Doing things such as not going out with his friends to stay in with his girlfriend and always talking about her. Being a nesbit is easier to spot if you knew the boy before his girlfriend and he then changed significantly on his route to nesbitdom.
EX 1 Tell you what, he has been a right nesbit since he started going out with her..

EX 2
