When a man gets just as excited as a fangirl over something nerdy, but is too mature to be called a "fanboy"
Man 1: Wow Doctor Who is such an amazing show!
Man 2: Are you a fanboy?
Man 1: On the contrary good sir, I am a "fanman"

Get the Fanman mug.
1. (usually used as an adjective or a verb) When either a boy or a girl fans so hard about something that they get a "fan erection" and therefore, is fanmaning.

2. When a straight boy/man fans over a boy who is usually famous, or a fictional character.
1. That girl has been fangirling about the anime Black Butler for the past hour. What a fanman.

2. That boy keeps fanmaning about Justin Bieber's new hit song.
