Glaswegian Swashbuckle 

The art of drawing an obscene amount of flem from your esophagus (or honking a loogie in colloquial terms), swashling it around your mouth like a fine Northern Portuguese drop of port then finally releasing said flem on an unsuspecting member of the public’s chest in true Glaswegian fashion.

Innocent bystander: Why Charles, i don’t know why I brought my pink Christian Dior Cannage stitched bag over my Louie Vuitton Canvas...

Person 2: Aye, why don’t you wear this instead ye posh cunt **spits a Glaswegian swashbuckle on her chest**

Innocent bystander: Oh the humanity.
