Paparazzo

Italy is the country where the business of selling snatched pictures of the famous began and gave the world the word "paparazzo".

Mennad is a paparazzo.

That man with the camera over there is a paparazzo.

You may decide to shove the lens down the throat of your aggressor, in the style of an aggrieved celebrity seeking primal redress against a mischievous paparazzo; but then again, most ecstatic rituals are pacific in intent and you may find such violence inappropriate.
