My most hated phrases are already listed- Can't be asked, At the end of the day, etc.etc.
My ultimate is when my MiL says, in her condescending tone, "Well, do whatever you like." I'm pretty sure I would've done what ever I wanted to-even if she hadn't said that. What is that?! Is she giving me permission or something?! Makes my head want to implode and never come back.
