Looks like it’s supposed to mean either to be hit with a glass bottle or mug, or slashed with broken glass; use of a glass object as a weapon in any fashion.
I haven’t heard “glass” used as a verb until now.
Having read the Daily Mail, glassed is a word the British use.
As a hunter, I glass my prey with binoculars. I thought someone was glassing some good looking babes here.
I may have come across it in reading about the effects of atomic bombs on desert sand.
Or, how about the phrase "...his/her eyes glassed over...".
Okay, neither applies to the actions of one or more glass bottle wielding wenches in Glasgow.
Thanks for the explanation! I’d never heard of being ‘glassed’ before.
I guess that happens when you make guns and knives illegal.
