Denver Dumpy

When someone has a butt SOO large their underwear sags and it looks like they are wearing a diaper.

John: "Do these leggings make my butt look big?"

Sara: "Oh yeah, you are rocking a real Denver Dumpy."

Telehubby

when your husband (who is your dad) dresses up as a large yellow/green/purple/red baby monster and you are no longer sexually attracted to their intellect.

Smith: "Hey Helen, what is your husband-dad dressing up as for Halloween?"
Helen: "He is dressing up as the Yellow Teletubby."
Smith: "Oh! He is going to become a Telehubby!"
