floor roller

A tantrum like behavior, usually exhibited by adolescent males, where a person will literally or figuratively roll around on the floor in a whiney & depressive manner. Floor rolling is most commonly practiced in the hopes of gaining sympathy and attention as a victim of some exaggerated personal tragedy that, relative to the rest of humanity, is miniscule.

Kanye was such a floor roller at the VMAs when Taylor Swift won that award, it wasn't about about him. Nobody gives a shit about his feelings anymore, he's been a constant floor roller for years since that tantrum on MTV.
