Somewhat New Word: Racktastic

I've learned adding '-tastic' to the end of any adjective makes it that much better. Racktastic (rak-ta-stik) adj. 1. A word describing a woman's cleavage in an unbelievably low cut shirt. Example: "Did you see that shorter chick though? They weren't big, but they were racktastic" 2. A word describing a woman with...well, an unbelievably large rack.
