اِنـطـم ('ntam)-----(stress on---tam) “Gulf” Arabic This word, in the imperative, means SHUT UP (or rather, in rude USA speech: SHADDAP---flap the “DD”) Is this term used in other dialects or at least understood by them? How rude is it really? Should I avoid using it? If I were to show up in Beirut and told someone to 'NTAM!, would he understand what I meant? Any comments appreciated.
