The word wanker is coming to mind because I'm gonna give most people who did this and pulled out a speaker with their face on it, it would look a bit, you know, narcissistic and weird.
Wanker is a term that literally means "one who wanks (masturbates)" but has since become a general insult. It is a pejorative term of English origin common in Britain and other parts of the English-speaking world, including Ireland, Australia and New Zealand. It initially referred to an "onanist" and is synonymous with the word tosser.
