It's like a movement of the head to one side, usually use when speaking in a sarcastic or patronising way to someoneCan anyone explain what this is actually supposed to entail? As in, physically describe the action because I literally don't understand what it means? With the tinkly laugh, DYMTBSR and 'are you on glue' I can at least picture the effect they're going for, even if I think it's lame. 'Head tilt' always makes me think of their necks lolling around like one of those floppy balloon men you get outside American car dealerships.
