A "straightedge" person was originally someone who didn't do any of the following; * take/use drugs * drink any alcohol * smoke * have sex * eat dairy products * eat meat now-a-days, most kids call themselves straightedge if they don't do the top 3 in the list, and any kids that don't do anything in the list are called "hardcore straight-up straightedge kids" Answer A straightedge is a piece of wood or plastic to help in drawing straight lines. A ruler is a straightedge, but a straightedge may not be a ruler. Both have a straight edge, certainly, but a ruler also has marked gradations for measuring things.
