The act of lubing up one or more fingers and inserting them into your bro's rectum. The general principle is that if your bro goes with the flow then he is therefore a "Brosexual". If your bro molly-wops you then he could just be "bro-curious". If he chops your dick off and eats it in front of you he is "brochotic".
Bro 1: "Broheim! Why did you let Joe give you a Bropository and giggle like a school girl?"
Bro 2: "I don't know bro, I guess I could possibly be Brosexual...."
Bro 1: "You need some serious Brosistence!!"
