I know you kid, but rolling without the DM asking you to is a dick move and a faux pas at a table. You really shouldn't do that. Same thing happened with Critical Role and the "roll for scry" moment. It puts the DM in a position where they might have to confront you, deny you the roll and sour a moment. It puts pressure on them to allow you to do something, which players often abuse - someone spins a tale of doing a quadruple backflip, landing on someone's head, attacking and bumping the dude into lava, rolls before the DM can say "there is no lava nearby but..." and puts them in a really awkward situation, especially with high rolls.
