Does Satan actually laugh? I've watched a lot of horror movies and I can't help noticing Satan or any demons are often portrayed 'diabolically' laughing somewhere in the movie. But then, Satan is supposed to be our prosecutor* at the Last Judgement and a professional prosecutor would NOT laugh for other reasons. So, my question is - are there any facts in the Book or elsewhere confirming that Satan indeed laughs?

* I got the idea that Satan will be our prosecutor from the Book of Revelation but please also explain that imagery if my interpretation is wrong.
"Laughter" has two completely different manifestations: it can be joyous or a cynical sneer.

Joyous laughter: not possible for Satan since Joy is a fruit of The Holy Spirit.

Sneering: not recorded in the Bible from Satan, but certainly used by his followers, see both in the Old Testament (Isaiah 57:3-5) and New when the Pharisees sneered at Jesus, both regarding His attitude to money and His failure (in their perception) to save Himself.

Personal note: I'm pretty sure I can hear the sneering when I read Biblical accounts of Satan, e.g. in his first appearance.
