poser bro 

Not a true bro. Someone who acts like a bro and pretends to bro out, but in reality they are just posing. They remain sober and leave their boys hangin for unbrolike activities.

Why isn't David drinking? He's sober and being the biggest poser bro tonight.
Noah's left us hangin to be with his bitch again. What a poser bro.

Bropose 

When you tell your buddy that you would marry them if they were female.

"No homo, but the girl of my dreams is the female version of you."
"Whoa man, did you just bropose?"
"Maybe..."

Broposel 

When a man asks his best bro to be his best man at his wedding. Sometimes making the broposel more elaborate and meaningful than the proposal the man gave his new fiancé

Kevin: Paul man you have been my bro for 10+ years and now I'm getting married, so now I have a Broposel for you.

Paul: uh...ok?

Kevin: will you be my best fucking man?

Paul: Fuck Yes Bro

Bropose 

1. The act of proposing to one's closest bro. It is an entirely heterosexual act, and requires the same level of commitment to eachother as in that of a bromance.

2. The act of putting forward an idea to one's bros.

1. Dirk: "Yo Brent, how was last night?"

Brent: "Oh it was rad dude, Chad totally broposed"

Dirk: "Wow that's awesome dude, i'm totally happy for you two"

2. (Dirk gets up at the table)

Dirk :"Gentlemen, i wish to bropose something, we should totally have a bro and sack night at mine this friday"

All : "What an excellent broposal"
