Slat (also known as
Plapp): leftovers at the bottom of a bottle. E.g. coke that is flat, and left alone to
foost at the back of the fridge for a few weeks. Cheap whiskey left over from a student party that tastes like
wood varnish, that no-one wants to touch. Taken from the Swedish: "Slat."
Olga:
Hej hej, if you want a mixer for your whisky, there's a slat of coke left in the fridge.
Fredrik:
Nej, keep that away from me, it's flat and there's an island of green mould on it!
