This state is characterized by an overall 'fuzzy' head feeling as if your skull was filled to the brim with a mass of wet cotton balls.

Origins of the term are unclear, but in the EDM scene, strong evidence points towards either the state of Florida or Texas coining the term, with Florida the more probable place (8up.com is a storied rave/party website for Central and South Florida).
