gray thickness

it is a horrid, wretched filthy entity that accumulates on the side of one's seat after the person blows their nose in their hand and wipes it on their upholstery daily. They also have a unsound assumption that boogers and snot disappear.

I will never ride in that bitch's car again after seeing that fucking gray thickness!! gag!!

Get a fucking tissue mom! All my friends see your gray thickness!
