I remember snark hunts from camp days. Newbies would be gulled into going out to hunt the snark. When they were sufficiently far from camp and after going in circles that they were 'lost,' we would sneak away. Sometimes called a snipe hunt. Great fun!

Also, a snarky person is one that that snaps at an inquirer or takes offence easily.

Never heard that snark has anything to do with a laugh. Urbanspeak?

To older people, a girl is any female under 50. Only Ava Gardner was a goddess.
