Well, for a while there, between BB8 and the people at work, the phrase "It is what it is," bothered the sh!t out of me! I've gotten over it...
John and his friend Dave have this damned phrase, "Are you snerious?!" from Little Nicky, or their variation of it, "Sneriously?!" Cyera picked up on it, and it bothers me to hell!
And though it's not a phrase, I can't stand the word "petted!" I realize it's in the English dictionary and it's a real word, but damned! I really hate it! Just say, "I pet the cat!" To me, "I petted the cat," sounds wacky!
