The consumption of alcohol in a social surrounding, especially to excess.
Derived from the Scots
toast 'slange var', traditionally said at dinner with the
right foot on the
table.
Aye mate, we were in a total slange
cave before we came to the club, so slighty the worse for wear.
Few more tins of Tenny's down ye and ye'll be pure slanged.
Tuesday nights are an opportunity for epic slange if you
aren't facing a breathaliser the morning after.
