When a male friend, (a bro) is acting like a girl.
"Hey, Brocahontas, stop doing your homework and come play beer pong!"
Bromigo: "Dude I want to invite Jessica but she's a girl and only bro's are invited"

Brosideon: "Jessica I dub thee Brocahontas. You are now a female bro and may now be brovited to the brovent."
Jessica/Brocahontas: "Yay! Thanks bro."
