"It is what it is."
My boss uses the phrase to excuse the fact that her business is failing as a direct result of her poor choices, i.e. "Boss, here are the numbers from December and here is the list of bills that are past due." "Well, it is what it is."
Jeggings. The word just irritates me.
Shortened words such as 'rents' for parents or 'za' for pizza.
