Lancaster "spitting chips" after Stage 2

Aussie Slang dominates reportage of their home boys at the Tour in Cadel Stays Cool On Tour de France. Even the "on" as opposed to "in" of the title threw me. What are they, New Yorkers?

Here are my fave's:

"Cadel Evans was content but fellow Australian Brett Lancaster was spitting chips after the first bunch sprint finish on the Tour de France."

"'The guy needs to pull his head in.'"

"Roulston came a cropper on Sunday when he crashed with 70km to go, according to his team, then he missed a split second decision which meant he didn't pull as planned in the lead-out."
