A combination of a crush, infatuation, and lust. This occurs when you feel like you could fall in love with a person you randomly meet and are only in their presence for a very short period of time. This commonly occurs when you least expect it, generally in an obscure setting. While these feelings are accomponied by intense sexual desire, a sense of deeper connection is prevelant.
While I was on vacation with my family, I met a waitress at a run-down seafood restaurant. She had brown hair, tan skin, pink finger-nail polish (which I generally don't care for but this was an exception), and a smokin' hot southern Belle accent. I definitely had an incrustuation on this girl of my dreams.
