When one Bro jumps on the back of another Bro unexpectedly then begins screaming "BRODEO, BRODEO!" acting as if they are riding a bull in a rodeo. The goal is to stay on the bro for at least 8 seconds or longer, while the bro being rode is tring to get the bro rider off. Just like in bull riding, in bro riding you use only one hand/arm to hang on. similiar to Icing in the way this is done between "bros"
(Bro Rider often acts like a cowboy while participating in a brodeo)
Bro Rider: "BRODEO YEE HAW, BRODEO! GET 'EM PARTNER!"
Bro: "no way you were riding more than 8 seconds bro"
Bro Rider: "some salt?"
Anthony: I have a date with Mat on Black Ops
Linda & Lamees: But didn't you have a date with Edward last night?

Linda & Lamees: ...What a brore!
Two men that have fallen into a deep and powerful bromance. Most obvious signs consist of forevertalking about or to each other via text messages. And constantly identifying each other as best friends.
