when you're eating an old woman's ass and she farts, covering you in dust
"i was tossing you're grandma's salad the other night and she grantiqued me!"
The social activity (or fetish) in which a group of older men - or young men with issues - set out to pick up women in the age group of most grandmothers. Basically, a troll hunt for GILFs
Hey, I'm not doing anything this Saturday, you want to go grantiquing?
