To ‘bite the big one’ is to die. But… the big one what?
Back in the '80s my friends and I would say so-and-so bit the big cookie. I don’t remember why biting a big cookie is deadly, but to bite the big cookie means biting the dust. ‘Bite the dust’ is an easy metaphor. Perhaps ‘bite the big one’ comes from it. ‘Bite the big dust’? Doesn’t really make sense.
So what is The Big One in ‘bite the big one’?
