The act of a perverted Scottish science teacher, called Nigel Gilson, swinging his rather saggy ballsack multiple times (to increase momentum) and plopping them on the corner of a students desk.
You won't believe it. I've just had a chemistry lesson with Mr Gilson. And worst of all, he done The Gilson Drop on my desk.

Get the The Gilson Drop mug.When someone of mass size is unable to breathe through their mouth due to excessive fat hanging (triple necks), so their body struggles to survive by allowing certain stretch marks to form into gills to absorb and intake oxygen

Get the cow gills mug.Very drunk. In British slang, "pissed" means drunk (not angry, like in the US), so pissed to the gills is like being so drunk, you're SWIMMING (hence, the GILLS) in alcohol.
