[[caption-width-right:350:Squirrels! Squirrels in my pants!]]
Let's say a character is just walking along, and suddenly they get a horrible itch in the middle of their back. There just happens to be some [[LeftTheBackgroundMusicOn music playing]], and as they contort their body to try to reach the itch (coincidentally in time with the music), people around them start to do the same thing, thinking it's a dance. It becomes a DanceSensation, and usually the character doesn't even notice, as they're still trying to get to the itch.

It often gains momentum when one person in the crowd yells, "Hey, look at those cool dance moves!" or something similar. That person starts doing the move, and pretty soon everybody's doing it.

Overlaps with SquirrelsInMyPants, as this is sometimes the reason for the motions. It also tends to be attributed to AgonyOfTheFeet.

The Icelanders, not knowing what's going on, start to mimic the movements.

* When Grape Ape stubbed his toe on ''WesternAnimation/TheGreatGrapeApe'' (episode "A Grape is Born"), he started jumping up and down, holding his toe and saying "Oooh, Aaah, [[CatchPhrase Grape Ape, Grape Ape"]]. Not only did nearby buildings get rattled, he also created a new dance.

* The Italian dance of Tarantella, according to folks, started out when tarantulas bit farmers on the fields. Since the folks thought the spiders' bites were dangerous, they danced until they sweat to drive the venom out. Other people then danced to the beat and the heat, starting a dance frenzy.
