Did some looking with google to turn up some info on the ones that haven't been answered yet.
EBB - I think is just ebb, either the player or the game is slow or not having much action(good cards).
ICM - Independant Chip Model? A program for analyzing games like SNGWizard.
Seattle Stew - No clue.
Rock - A very conservative player.
Tricky - A tricky player.
Fish and Stew - Pocket Jacks
Could be wrong with all of them though, that's just what I could find in a few minutes of searching.
Oh and FTW, in certain MMORPG's someone saying "player x is FTW" is a compliment, basicly saying they're a good player. In a couple others I've seen it used sorta sarcastically as someone already pointed out. So it does depend on the group and the setting.
