A word of Arabic origin meaning "look!" Was brought back to Britain after the Second World War by returning soldiers who had learnt the word from Arab peddlars of dirty postcards. The peddlars used to keep the postcards hidden inside their coats and would show them to soldiers saying "Shufti, shufti!" - "Look, look!"
"Take a shufti at this!"
To have a quick look, a rummage through.
Alt. spelling: Shufty
"I'll just have a shufti through these papers for you."
