(U.K.) Tea.

Word used in the British army during WW2.

Possibly related to 'blech', from from the German by way of Yiddish, word for tin or sheet metal, - a metal sheet used by many observant Jews to cover stovetop burners. Or perhaps to the German word 'platsch' or 'platschen', - a small puddle or splash.
