1. (noun) One who kills the flex.

The Flex Killer, most often a female, kills the flex of surrounding individuals by eliminating any shred of happiness or joy present.

By sucking the life out of every enjoyable situation, the Flex Killer quickly becomes a widely feared and hated phenomenon.

They can be spotted most frequently at social events, geographic locations and even government-funded institutions (i.e. Prom, Wasaga Beach, Thornlea Secondary School, or in the general Thornhill region). This makes the Flex Killer a truly dangerous individual, and one to be avoided at all costs.
*Individuals gathered around enjoying the flex*
