"sick flex" is a reference to two pop culture points of interest. "sick" refers to the mid charting hit "Down with the Sickness" by Disturbed that broke the Billboard top 20 in 2007. "flex" is an homage to the late Billy Mays due to his relentless pontificating on the water-resistant properties of the made-for-tv product Flex-Seal. In essence, you are both down and sticky, a condition we refer to as "Peter Northed".

Get the Sick Bitchmug. When one sick individual in a couple just can't keep his/her mouth off their gf/bf/fuckbuddy, passing on the virus that they will eventually get back from said gf/bf/other, creating a vicious tennis-like volley of sickness. The world must know.

Get the Nostalgia Sicknessmug. The state of being mentally removed and detached from corporate business culture, and general disgust from the overconsumption of business buzzwords and acronyms.
