Grandpants

An old man who fought the Japs in WWII and sends you $100 dollar checks which signify the approximate amount of love directed at you. Carries the name "Grandpants" due to the high position of the Sears Docker Elastic pants he wears above his hip bones. He also loves Spaghetti and Meatballs at Dinos, hates awkwardness and negroes. Favorite phrase is "Ehh your a good kid Brendan, I live next store to the niggers."

Synonyms: (Crampon, Pants-Pants, Grandpon, Uhhh Mary)

Grandpants called, he said we have to go to the holy immaculate feast of St. Anthony's for clams and buttered shit.
