Tips To Keep You From Sounding Stupid

Today's tip to keep you from sounding like a moron: If you feel a need to use abbreviations, at least first know what the abbreviations stand for. That way, you won't utter such foolishness as "PIN number" and "ATM machine." For those who don't know, the "N" in PIN stands for "number," and the "M" in "ATM" stands for "machine," so if you say "PIN number," you are saying "personal identification number number."
