Depends if goofy and dippy are the same things. I am fairly inhibited, and unintentionally am really stupid at times. Put it this way - I'm blonde, and I'm a viola player ...
Have to say though, only with my friends, or with acquaintances with whom I feel comfortable am I goofy when I realise it. I will happily go hyper or get hysterical (laughter) with my friends, and do weird stuff, because they know me. Same goes for said acquaintances, but not for many other people. So it depends really.
