Using "addictive" as a postive attribute comes to mind. Portraying addiction as a good thing because exploiting addicts is profitable is downright sociopathic.
"the proof is in the pudding". Why say that? It's meaningless. It's meaningless because it's wrong. It's a mangled chunk of the original saying, which does make sense. It's like people saying "I could care less" when they mean the exact opposite.
Almost all "business buzzword bingo" nonsense, starting with "going forward". Why not just use English when you're using English?
EDIT:
Oh hell yes! "really unique", "more unique", etc. I want to reply "If you don't mean 'unique', why are you saying the word? Why are you talking nonsense that contradicts itself? Why? Why?"
