slat 

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!

Slat 

A combination of the words 'slut' and 'slapper'. Usually used to describe a girl who will hook up with guys, stringing them along, never taking it any further.

A slat can often be a tease, dressing and acting like a slut, dancing on tables in a bar. If hit on and asked to come home by someone, a slat will get offended, physically or verbally 'slapping' them and storming off. Thus the name

That girl is such a slat, I've been trying for weeks and I still haven't got any

Guy 1: Emma is such a slut

Slat 

A person who is very ghetto and who does not have a good sense of style. They tend to originate from the bad side of towns. Slats or slatty people usually are also known as gangsters. They tend to take pictures with thick eye liner, stupid faces, and they hold up the area of town they "represent". Ex. Make an "e" for east side, "w" for west.

1:Did you see that girl wearing a all black long-sleeve in the middle of summer?
