1. Destroy. 2. Beat (Australian Concise Oxford Ditionary)

Trounce, Do for (Concise Oxford Dictionary)

It’s a word my grandmother (on the English) side used to use, but I had forgotten about it until this morning when a colleague mentioned it as a nonsense word that her grandmother used to use. I had great delight in telling her that it wasn’t actually a nonsense word and we looked it up in a dictionary and lo and behold – there it was.

But we were in agreement that it’s definitely a grandmother word.
