Someone who simply can't stop moving whilst they're awake, often wrongly accused of being drunk or high.
Originated from Algerian musician Khaled's song "Chebba" (an Algerian dance song). Khaled - the King of Raï - wrote songs that confronted the Islamic taboos of drink and drugs.
Chebbas often contract Festivalitus.
"Freddo, what's wrong with you? You can't stand still while im talkin to you!"
"Sorry Dev, I was born a Chebba." (whilst jumpin up and down)
