Hermione: Hey Harry, how did you deal with all those death eaters near Hagrid's cabin the other night?
Harry: I used the 'stupefy' incantation to stun them and I hid them in the Forbidden Forest while they were still unconcious.

A term used in moments of hilarity, complete randomness, or hyperness. You point weirdly at your friends, acquaintances, teachers or complete strangers and say 'Stupefy!' in a silly voice, thus causing much laughter.
*Person walks along the street past you and your friends*

You (once they are mostly out of earshot): Stupefy!
