When you’re with a hot woman, and you insert a can of ready whip into her touchhole, and pull the trigger, fill with cream and void, and pop it out. Have her fart the whip cream on your face, and you scream “WELL HELLOOOOO!” In your best Mrs. Doubtfire.
I heard Freddie is a whip cream fanatic, even got the Dirty Mrs. Doubtfire from Yeates.
