I have a character in Texas who passes on a threat through a third party in Mexican Spanish.

The line is something like:
'You tell him I said: watch out'

Where 'watch out' is written as the Spanish equivalent but the 'You tell him I said' remains in English.

I've spent a long time Googling this and the best word seems to be 'aguas', but the more I read, the less certain I'm becoming!

Would 'aguas' work?

'You tell him I said: aguas.'

Thank you!
