It's actually named on Wikipedia, where it describes it as:
"Stealth disco (or SD) refers to the act of being videotaped dancing or rocking out behind or near someone who is doing something serious and does not notice. This is sometimes referred to as stealthing (or SD-ing) that person, a process which often concludes with emailing them the footage."

Try it at work!
