Uncle Grandpa 

That grandpa you have that lives by himself in that bigass house. He's loaded. He's got that big shiny SUV. Always got his prescription sunglasses on. Wears a hat even while inside. Socks and sandals all day bitch. Unless he has his fly hi-top blue sneakers or boots. Goes to the bank to get you your fat weekly allowance. In his pajamas. Makes everybody call him Uncle *insert name* You could totally see him in a rap video.

Jake: Howie your grandpa is so cool.

Howie: That's Uncle Grandpa to you.
