Fruntalot is a clothing company in Grand Theft Auto IV and Grand Theft Auto V. It is featured on Peepthatshit.com in the "Hip Hop" section, as well as on a billboard in Algonquin. Fruntalot is most likely a parody of FUBU.
The person pictured on the billboard in Algonquin has gained notoriety among players, since he bears a striking resemblance to Carl Johnson, the protagonist of GTA San Andreas. This is highly unlikely, however, since Carl Johnson does not exist in the HD Universe. The Fruntalot clothing is sold in Sub Urban and Checkout! stores.
