A fun-loving acitivity that family and friends may participate in. It is similar to American baseball, but played in a pool where the team size may be anywhere from 2-5 players per team. The "bat" is a foam rubber whale and the "ball" is a mini-volleyball. Singles, doubles, triples, home-runs, foul-outs, strikeouts, balls, and foul-balls are all incorporated into this game thought up by the geniuses from GH and Lompton.
"Yo man, you see me jack the whaleball over the neighbor's fence? Shit. I put that thing into orbit!"
"Let's kick off the day with the inaugural game of whaleball."
Eating so much you turn into a whale and then you get pushed into the ocean when you go to the beach because you're mistaken for a beached whale
Oh man I ate a bag of m&ms and a bag of skittles and some chocolate wafers and washed it down with a carne asada burrito. I'm suffering from whalebesity!
Basically in it's most literal sense it means "one who fornicates with whales" but it is a very diverse term and can easily replace a few of the swear words you'd normally use.
