Dismissively is how you do something when you will not take it seriously: you speak, look, or wave someone away in a way that shows they do not matter to you right now. The word sits on the way you act — the voice, the hand, the short laugh — not on the person themselves. It is the same grown-up, slightly careful word as dismissive. Though actually, English speakers often show this with the body more than with this long adverb. When someone does use dismissively, they are usually describing that cold little push-away in a story or a complaint.
