NAGMF - A NAGMF is a guy who can't get a girl and won't stop trying.

A NAGMF is a guy who can't get a girl and won't stop trying. He drinks, he yells, and he blames everyone else for his problems.

I tried to impress a girl. She said I was a NAGMF. I got drunk and yelled at the bar.

My brother is a NAGMF. He texts girls, then forgets to call them back.

I told my teacher I was a NAGMF. He gave me detention. I deserved it.
