Blue Seat Studios' Tea Consent explains the idea of sexual consent through the act of offering someone a cup of tea: it's OK to offer someone a cup of tea, but if they don't want it, then don't try to give it to them. And if they change their mind after you make them a cup of tea? That's annoying, but still, don't try to make them drink it. And unconscious people? They don't need a cup of tea. (via Kottke)
