1. People who start by saying, "I'm just the kind of person who..." followed by some characteristic common to any normal, sane person, as if this somehow makes them unique: "I'm just the kind of person who doesn't like to wait in line." (Oh, gee, the rest of us love waiting in line.)
2. ANY altruistic wish expressed in the imperative: "You have a nice day, now!" I could never stand the chorus to Jesse Colin Young tune, "Come on people, now, smile on your brother. Everybody get together GOT TO love one another right now." Got to? I think not.
3. The expression "Don't go there." But this one is so lame, it has already been excoriated nearly everywhere.
