A brotilla is a formation of floating bros that may be part of a larger bro fleet. Commonly found in tubing rivers, these man-rafts often carry red plastic cups, and may be heard inquiring: "Where are the chicks?"

A brotilla has no direct equivalent on land, but is, perhaps, the rough equivalent in value of a brogade.
