The literal worst NFL team you can find. Never won a Super bowl and possibly may of never won a game, so if go to Cleveland, you know your NFL team will always be better then them.
The Cleveland Browns suck balls
Based on the scene from Family Guy where Cleveland Brown falls from a tub off a broken house after "Peter's shenanigans", Cleveland Brown-ing is just that.
"Honey, why is the neighbor on the roof again?"
"Its fine, he's just Cleveland Brown-ing again"
