Man's Gooning Shirt in Public

Alright, listen up, you big brain! You see this happy old dude, right? He's just vibin' in the store, pushing his cart. But look closer at his shirt, you genius! It says 'I love GOONING'. Now, 'gooning' is a term, often from the internet, that means a certain... *self-pleasure activity*, sometimes drawn out. So, your man is unknowingly (or knowingly, who knows, you aren't that smart to tell the difference) advertising this, uh, *hobby* in a very public place. The humor comes from the absolute wildness of an older person wearing something so niche and often explicit, completely out of context. You probably thought it meant something innocent, didn't you, you silly goose?
