If my friend was getting water from the well and got his pants wet, could I say jocularly to him "Have you been pissing upwind "? Would it work in English?
Would there be an expression to describe that?
We say spit in the wind, so I would use in.
"into the wind"
You should also know that "pissing" is mildly vulgar. I'd crinkly my nose in mild disgust if I heard you say it.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
