Brosturdation

Going out with your bro to movies or restaurant because there is no chick willing to go with you.

Dude, you should stop that brosturdation and rather ask some girl out.

Brostruation

When you notice one of your bros is acting like a little bitch its safe to assume that he is suffering from brostruation.

Guy 1: Dude what's up with John?
Guy 2: It's his monthly brostruation.

Bro:1 I wonder if he's brosterbating to us right now
Bro:2 I hope so
