Phrase depicting the line of Toyota hybrids seen in the carpool lane on the 405 freeway, most often during rush hour traffic.

Also a phrase used to describe the intense jealousy one feels towards Prius drivers for getting carpool lane access while the rest of us rot in bumper-to-bumper traffic.
"Gosh, the Prius Procession was unusually long this morning. Those liberals must love the privilege of using the damn carpool lane."

"Did you see Becky's new Prius? Yup, she's joined the daily Prius Procession. That bitch."
