The tendency to mumble unintelligible or foreign-language verses to popular songs before loudly shouting notable phrases. Named for the rapper Shaggy, of "It Wasn't Me" fame.
The Shaggy Effect in it's original context:
-How could I forget that I had given her an extra key, all this time she was standing there she never took her eyes off me
