Melt has to be the most used word on this forum
Never see it used anywhere else
Melt has been said by people from London/Essex for donkeys years, and it just used to mean someone was an idiot. A bit simple. Dim. A melt. That's the way I always heard it used (never directed at me of course haha...)
Now the internet has decided it means people being angry, short for melting down I suppose.
Either way, this place is full of melts.
