Meaning of the phrase 'Take the p**s out of...'

Could you tell me the spell of P**s ?
And the meaning of the phrase.
Thanks!

Hi floratang

I assume the censored word is “piss” and the expression is:
“take the piss out of someone/something”

This seems to be primarily a British expression meaning to “mock or ridicule someone (or something)”.
