A dance move in which a person does the Macarena but instead of turning to the side at the end, they continue shaking their ass until the end of the next Macarena. They then perform the Macarena backwards and shake their ass until the end of the next Macarena. They repeat this throughout the entire song.
Example:
*Does Macarena normally*
*Shakes ass until then end of the next line*
*Does the current line backwards*
*Shake add until the end of the next line*
*Repeat through the whole song*
