A gay Puerto Rican kid who sells shoes made from tires so he can eat. Then he kicks you in the balls then steals your wallet.
"Man, that kid keeps asking me to buy shoes so he can eat" Said Julian. "Ignore him, he's just a stupid Rios" Replied Alex. "That fucking Rios just nailed me in the balls!" screamed Alex. "He's running with your wallet" Replied Julian.
