Words and Expressions That I Hate

Cheer up/Chin up:  Seriously, what a shitty thing to say to someone. It devalues that person's feelings, and it suggests that everything would get better if they would just smile a little, gosh!

Morning, Sunshine!:  Ok, maybe it's because I'm not a morning person, but this makes me want to punch the speaker in the face. In the same vein...

'Morning! or 'S good! or any other shortened, abbreviated expression, especially in writing:  I have no good reason why this pisses me off so much, but it totally does. It just comes off as very...precious. And twee. Twee is never the way to go.

Dovetail:  I seriously hate this word so much, and I can't explain why except to say that I find it super pretentious. If you use this word, I will probably decide you are an asshole.

 Natch:  It wasn't cute in the early 90s, and it's still not cute.
