Slarge

A measure of wine.

When the bartender asks your lady friend if she would like a small or large wine, with good intentions she starts to order a small.
But due to being a borderline alcoholic she can't resist but change it to a large.

gentleman "a pint for me and a dry white wine for the lady please"

bartender "small or large miss?"

lady friend "I'll have a Sss... slarge please"

gentleman under his breath "bloody lush"
