Definition One

When something beyond comprehension has happened to you or some one else you know, positive or negative you say the word peak to portray the sheer level of OMG

Peak times are times where life has thrown some crazy stuff at you and everything is just WOAAAAAAAH.

Usually a hand sign is involved which symbolises a mountain peak. If something is that deep the word doesn't even have to be said, you can just do the hand sign

Definition Three

“Peak” is the truest embodiment of the north-south divide. In the south, the masses - disoriented and confused by the brightly coloured Pret and Waitrose signs - think peak means bad.
In the North thankfully sense still reigns and peak is good.

Sometimes said "Peak Times", the word refers to an event to be or in the past of enjoyment. Alternatively, the term can be used sarcastically in a bad situation showing your lack of enthusiasm.

Dave: Mate, you coming to the party on Saturday?

Eg2:
Matt: Ahh I'm totally screwed for and exam, I've done no revision!
