G.H.F.
A guy who thinks he’s a rockstar, but he’s just bad at everything.
My friend is a G. H. F. He tried to sing at a karaoke bar and everyone ran out.
My dad’s a G. H. F. He wears a hat every day and thinks it makes him cool.
The guy who tried to dance at my birthday party is a G. H. F. He looked like a confused robot.
