An older woman in her sexual prime, on the hunt for younger men (also known as cougar) who's vacationing on a cruise ship.
As my buddies and I relaxed in the hot tub aboard our cruise ship, a crugar approached. She seemed to be licking her chops, ready to devour us in the scalding hot water we were already stewing in.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
