The phrase queer attitude used to be commonplace, simply meaning a strange attitude or unhelpful behavior.
Unfortunately in the present era, I once used that phrase and sadly offended an LGBT person, since people today use queer to mean homosexual.
I can avoid saying queer attitude by just saying strange attitude.
What's a modern alternative to the common business phrase "queer the deal" that doesn’t risk giving offence where none is intended?
Other queer- phrases are easy enough to replace, but I am stumped on this one.
(Funnily enough the other day I gave someone the long-winded alternative: “I’m trying not to talk about it to not upset my negotiation so don't find me rude but I’d rather not go in to details, etc.”, and my colleague immediately responded “Oh, you don’t want to queer the deal, got it!” Geesh!)
