I'm not saying that to show elation at the word, but instead that is the word of the year...the interjection (to show excitement or emotion; They're generally set apart from a sentence by an exclamation point, or by a comma when the feeling's not as strong) "w00t". Somehow, "w00t" beat out "quixotic".
PS: Here's some keen stuff about whale songs.
PPS: Edited for accuracy (thank you, harmless_drudge!), since it's the 1337 form with a zero in place of each "o". The font that The Boston Channel used made it hard to tell "0" from "o".
