I’m thinking in particular of the middle-aged suburban woman I overheard in the cereal aisle last evening comparing various brands with her son, but this advice is pretty generally applicable: Please do not pepper your speech with expressions like “Yo!” or “check it out” or “da bomb”.

Oh, and please do not use “rock” as a verb unless you are speaking of boats, cradles or earthquakes.

You may think you sound cool but trust me, you don’t.

That is all.
