It's a word used to describe someone who somehow manages to piss on their feet while standing at a urinal.
*Ben walks into the toilet*

Matt says : "Oh my god, Ben's pissed on his foot again, what a 'piss foot'."
Ben says "Naa.. Rubbish man, it was from the sink, give me a break!"
Matt says "No way, from now on you'll be known as 'piss foot'"

Get the Piss Foot mug.
To tell a fabrication in such a way as to be ridiculously transparent; misleading; doing one thing, and purposely mislabeling it; bold face liar
Don't pretend that's as low as the price gets,I know the blue book value of that car, and its about three thousand less than what you want, so don't piss on my foot and tell me its raining! or I saw you kiss her, thats not how cousins kiss, so don't piss on my foot and tell me its raining!
