So i was watching Dodger play 'Panzermadels Tank Dating Simulator' and the Gunnery Sergeant, or the Teacher, at certain points in the game will talk about 'Skull Fucking' you, and she was joking about "what if you could romance him" and then when I was on my way to school i just had a random thought, our skull is in our heads, technically wouldn't fucking someone's mouth also be classified as skull fucking?
