Gratuitous Rap

Basically, things like characters performing brief rap numbers in stories where it isn't the primary subject.

Compare Piss-Take Rap and A Wild Rapper Appears. Hopefully unrelated to Gratuitous Rape.

Examples:

Anime and Manga
  • Gintama: Katsura and his "Katsurap."
    • Even more gratuitous are the recaps for the Thorny Boys arc.

Film

Live-Action TV
  • The Ringmaster in the Doctor Who serial "The Greatest Show in the Galaxy".
  • Degrassi Junior High constantly. The worst was Rick's environmental rap.
  • Champion ice skater Katerina Witt suddenly and bizarrely breaks into a full-on rap during one of the Christmas TV specials she made in the early 90s.

Video Games

Web Comics
  • Minion Comics features a Teddy Ruxpin-esque stuffed turtle singing a rap song entitled "Punch Your Bitch In The Mouth" advising schoolchildren about how to treat their girlfriends.
  • Homestuck, with GameBro, which doesn't seem to have any specific character performing it, but is a rap about an obscure plot element that resurfaces a negligible amount of times in the massive comic.

Web Original
  • Commentary! The Musical, "Neil's Turn": in the middle of a song he suddenly starts rapping.
    I'll charm the chicks (Are those real? Ha!)
    Do magic tricks (Was it the three of spades? Ho!)
    Lay down some tap
    And I can rap
    My name is Neil and I'm here to say, *random rapping noises*
    No I can't rap
    That was painful...
  • The cover version of "Splash Free" in 50% OFF adds a rap featuring Nagisa.
