Have A Cup Of Tea.
Refers to an exclamation of surprise or of general humour. You would HACOT, for instance, if an old work colleague sent you a picture of yourself from many yers ago. Back then you may have had hair, not worn
glasses and maybe even had your own teeth, you might even have been wearing Wrangler
stretch denim jeans - Have A Cup Of Tea, HACOT!
The act of actually having a cup of tea is spurious and more generally refers to the act of taking time out or having a
break due to the impending hilarity or embarrassment of the situation.
