Hubby or Hubs
The phrase "on trend" really irritates me.
Any number of corporate buzzwords. A coworker of mine just learned the phrase "hot dot" and will NOT let it go.
Also, any use of invented sci-fi curse words-- probably because a really irritating person I used to know used them constantly. Whatever the reason, I find myself tuning people out once those words come up. Frell, frack, you know the ones. It is for this reason that Stephen King's "Lisey's Story" is not higher on my re-read list ("Smuck," Steve? Really?!).
