The collective noun for "empties" is "tragedy".
It's good form to provide an illustrative usage sentence when introducing a word. I neglected that with "slab", so here we go...
Three Aussie guys were working on a high-rise building project -- Steve, Bruce and Kevin.
Steve falls off and is killed instantly.
As the ambulance takes the body away, Bruce says, "Someone should go and tell his wife."
Kevin says, "OK, I'm pretty good at that sensitive bloke stuff, I'll do it."
Two hours later, he comes back carrying a slab of Victoria Bitters.
Bruce says, "Where did you get that, Kev?"
"Steve's wife gave it to me,"
Bruce replies. "That's unbelievable, you told the lady her husband was dead and she gave you the beer?"
"Well not exactly," Kevin said. "When she answered the door, I said to her, 'You must be Steve's widow'.
She said, 'No, I'm not a widow.'
And I said, 'I'll bet you a slab of Victoria Bitters you are'."
Defined "sensitive bloke" while we were at it...
