uncle grandpa is from a tv show with the same name. Basically he came to be because your grandma adopted her husband. Therefore, he is you uncle and 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.
You have intercourse with you’re mom and have a sister, then have intercourse with her and her child will become your grandson/granddaughter and it will be your sisters kids so your also a uncle grandpa
An inappropriate Cartoon Network show about the child of a man who screws with his niece: so their child’s paternal uncle and maternal grandfather are the same person.
When your Step-Grandpa has an affair with your biological aunty, then marries her. Technically not insest, but still immoral.
He used to be my Grandpa by marriage (step) but had an affair with my aunty, so grandma kicked him out and he married aunty. He used to be grandpa, but now he is my uncle ... my uncle grandpa
