A brodaddy is a generally fratty dude who spends most of his time drinking beers and playing Wii bowling. He is usually outgoing and somewhat loud, sometimes to point of being obnoxious. Refers to most people as a bro, even girls. This is what separates him from a bro, even a sweet bro. Attire includes a collection of Vineyard Vines, Patagonia, and backwards visors. Will evolve into a yuppie when older.
That brodaddy we saw at the ultimate frisbee tournament was prettysweet.
