Shoal

The tendency for cyclists to pass in front of other cyclists who are stopped at red lights. Eventually over time, more cyclists will queue up in front of the group, and the group will stick out into the intersection like a sandbar, hence the term shoal.

A person who shoals is called a shoaler.

Reference
Coined originally by Eben Weiss on his blog BikeSnobNYC, the reference is to a term for a sandbar.
