Broooo is either just a long spelt bro or if a sister says it to her brother that means they/she wants to do some fun thing in bed together

A strung out bro is when two guys do the exact same thing at the exact same time so the two guys will whisper "broooo" after the epic moment the two guys just experienced.
Bro1: "Bro, were you just singing the same song as me?"
Bro2: "Yeah bro..."
Bro1 and Bro2 in sync: "broooo"
Bro2: "Yeah bro..."
Bro1 and Bro2 in sync: "broooo"
