Valley Girl Power!

OMG, who started this?!  This being a style of talking like Hollywood's Valley Girls, with a nasal, "little girl" style, hands tucked close to the chest, and "like" being interjected after every other word.  It's horrible, ugly, inane, and certainly unprofessional.  And it is heard everywhere, even among professionals.  Like, when asked to answer a question, you know, like, if you're at an interview, and like, you're sittin' in front of a prospective boss, and like, you want to present yourself as knowing what you're doing, like, you know, you majored in something important in college, and you even have, like, your master's degree, but like, it hasn't made much, like, difference so far, but, like, you're applying for this job, and like ... Ugh!!! GROW UP!  None of those "likes" is appropriate here!  And if you sound like a 10-year-old, no one will take you seriously.
