Impossible pairs

I admit it, I stole the title :P You can check out the article here.

There are some things we just forget...for example, The word “collision” is defined as an accident involving two or more moving objects, usually vehicles.
So we can't say “Six teenagers were seriously injured in a horrific smash last night, when their car collided with a huge gum tree on Quakers Road in Marayong in Sydney’s far west.” I've heard that before, but I had forgotten it...

And did you know that the correct expressions are either centre ON, or CIRCLE/REVOLVE around? (and not centre around)

The best one is this: “The audience’s response to the superstar tenor’s performance was so thunderous, their applause literally brought the house down.”
(Ouch!) Now this one I didn't forget; literally is a dangerous word and musn't be used unless if you really know how to! If you don't know what it means, you'd better look it up, 'cos that sentence pretty much describes a(n impossible) catastrophe!
