You play Roblox with friend and your idiot brother joins silently and someone else kills him, he screams and rages because he’s a little brother, then mom makes you get off and let’s bro stay on
A McGoobie brother is a close friend that is willing to help you with sexual release, but maintain the boundaries of friendship. This is often done by standing behind an individual with a mirror while performing a reach around, so the receiver believes that they are relieving themselves.
Person 1: "Hi Mate, I'm feeling a bit frisky. Care to give me a McGoobie?"
Person 2: "Sure thing, let me grab a mirror. I am your friend and McGoobie Brother"
