We have often wondered if "shitfaced" meaning drunk was a regional thing (from the Prairies).

This was in common use when I lived in a house in London, along with a Glaswegian and a couple of Cornish people whose father hailed from the Ukraine.

Well, that's interesting, because there are a lot of Ukrainians in Manitoba. My Newfoundland source says it's not as commonly used here (where the cultural background is 97% Britain/Ireland/Scotland/Wales).
