My Dad used to say "Strousers" as he thought it was more polite/less blasphemous then "Struth" (God's Truth).
So now we're back to lower body garments: apart from knickers we might say pants (as meaning underwear), whereas, I believe pants in the US are what we call trousers!
And I think what we call Durex is like Sellotape (sticky tape)in Australia?
