This is typically associated with the gay Hanky Code and if worn on the left, it means that you like to fist guys; if worn on the right, it means that you like to get fisted. UNLESS there is a white stripe and then it just means that you like to shave or get shaved or a black stripe denotes you are or like bears.
I caught Mark at the bar last night with a red hanky on his right arm; I had no idea he was into fisting.
The act of blowing your nose by a combination of covering one nostril with a finger and clearing the other with a powerful nasal blast of air, for use when a suitable snot receptacle isn't available. Popluar with farmers and footballers and useful in the right situation, but not really acceptable among polite company. Unless you're desperate of course.
A derogatory term for one who rides a Harley Davidson (or other cruiser style motorcycle). Hanky denotes the black bandana they are wearing on their head. This is worn in addition to their leather ass-less chaps, black boots, and denim vest. This is their idea of promoting they are bad asses (lol).
Look at that hanky head and his trashy broad. She looks used and abused and has sugar glider wings as tricep muscles.
