A person in the interior design world who practices their craft from a high and mighty perch. There's a lot of hand waving and pillow chopping in a decorina world.
We met the decorina today to pick out an armoire and her shoes were worth more than my car.
The fine social con of bringing a person as your date to an event such as a wedding to give the impression you are in a serious relationship when you are not.
As he was merely decoying, primarily for the benefit of his ex, he made sure to add to the impression by not being able to keep his lips and hands off his stunning partner throughout the evening.
