Yes, cycling fans, with the Tour at hand the commentators'll be using lots of unfamiliar language, and as I've already done at least 1 dictionary in years past, I'll keep this one short'n'sweet:
Allez: what you yell at the cyclists to encourage them. Example: "If you *ever* try to leave this team again, I'll have my goons drag you down that allez and break every bone in your body!"
American: the retina-burning abomination running alongside Lance dressed in a Speedo, a giant foam cowboy hat, and the Stars and Stripes painted across his gut. Use: "I can't believe we can't beat the !@#damn Americans in our own Grand Tour!"
Climbs: climbs are divided into Categories: Cat. 3 (small), Cat. 2 (medium), Cat. 1 (large), and Hors Categorie or HC (holy crap!). Example: "HC, I can't believe Vinokourov made it up that thing so fast unassisted!"
Cracked: when the clean rider that can't keep up with the dope-stuffed autobots who're about to take the podium. Example: "Cadel Evans has cracked!"
Directeur Sportif: if you're not Lance Armstrong, he's your boss. If you are Lance Armstrong, you're his boss.
Doping: what there wasn't a single instance of during last year's Tour, and what there won't be a single instance of this year, either. Usage: "I have never tested positive for doping. Suckers."
Enjoy myself: what you're at the Tour to do when you've just realized you're gonna lose the overall.
Entire annual steel industry output of China: what Stuey O'Grady's got holding his body together after 968 consecutive crashes. We love Stuey!
Gods: Phil Liggett and Paul Sherwen. Kneel, beeyotches!
Musette: the little cloth bag of food the riders pick up on the fly in the feed zone. Usage: "I'm sorry, Lance, did I accidentally toss my musette into your chain ring?"
My Grandma's: the blood bag/syring/white powder/notorious doping doctor found in your hotel room.
Promotional item: what you just sliced Thor Hushovd's arm open with two feet before the line. You idiot, you just lost him the stage!
Road rash: when you rip your skin off in a crash. Example: "if you drop me in the mountains when I need you, I'll give you !@#$ing road rash you weakling!"
Sprint: what Mark Cavendish interferes in to screw you out of a stage win. Wanker!
Stomach ailment: (1) a stomach ailment; or (2) what you suddenly drop out of the race for the night before the race organizers announcing your doping poz. Alternate use: "Man, I said I was coming back to win, but then Contador kicked my !@#. Must've been, um, that pesky stomach ailment!"
Team Car: where your DS keeps the little cooler with the "Fanta" in it.
Water bottle: what gives you a total bull!@#$ excuse to hang on to the team car for half an hour when you're about to croak on a climb. Usage: "Oops, the cameras are on us--I better 'pass' you another water bottle!"
Well, that oughta hold you all for this race. And hey, Buster--quit staring at my tete-de-la-course!
