One that I hear and grit my teeth to, is "Addicted". I hear too many people talking about something they like say, " I am so addicted to that." My 25-30+ kids use it, and older (than my kids) coworkers have used it.
I don't mean to sound preachy, but when you have lived with someone who has an addiction of any kind, it can be annoying to have the word used all the time like my youngest does, simply because he likes a product.
The other one is "you know". "I went to, you know the movie, you know and saw Beaches, you know and I am now addicted to that movie, you know?"
Sorry... Actually I think we all use a phrase or word to excess at times, and it takes a conversation like this one to make us think about what we say too much, and ways to stop it.
Happy Day!
