Qwatch
Qwatch - also known as eye boogers - is an accumulation of semi-dried mucus that forms near the area of one's eyes. It occurs when an individual wakes up from a long sleep, just to feel a ball of squishy sludge hanging from their eyelashes. It also occurs when someone has hay fever or a type of illness that causes their eyes to water profusely. If left unattended, it will moisten up and cling onto your eye whites, temporarily blocking your vision slightly. When you blink, they tend not to go.

Although qwatch is beneficial for trapping dirt in the eye, it does not look very appealing. Hence why it's on the infamous list of 'conversation killers' - something that stops people talking to you (eg. Dried spit or food stuck in one's teeth).

Qwatch can be rolled out and rubbed onto surfaces like boogers from your nose. They are small enough to be undetected and pose no serious threat when rubbed on walls. However, be careful not to shake someone's hand and be especially careful that your fingers are clean when rolling the qwatch out.
"Damn, Tyrone. Man has got bare Qwatch in his eyes. Wash your face, blud."
