taking a cheeky break during a long day at work by having five or ten minutes sat on the throne doing nothing..
or possibly a one minute power pooh followed by nine minutes of just sitting and relaxing..
Roger: I'm knackered man.. been on my feet for two hours now.
Bill: nip for a shit down mate, you've deserved it.
Roger: yeah, good call. back in ten.
A prominent English grammar teacher at Fenerbahce High School in Istanbul, Turkey created a new meaning of shit down in the 1990's as defined below. Unfortunately, the English-speaking world has known nothing about this contribution. I am very proud to present it here as one of her students. Learn and widely use it, please.
shit down (v):
1) (order) to tell someone to sit down when they fail to answer a question properly.
