A Birthday nazi is someone who's over excessive about celebrating someone elses birthday, usally/especially when the birthday person isnt a willing participant in the over-the-top stupid display of fakery.

See: Taking a veggie to a steakhouse or having cake and ice cream when someone on a diet.

It's my 22nd birthday and I just wanted a quiet night in. But Lauren had to be a Birthday Nazi and brought a bunch of people over and they all tried to drag me to the club.
