look up any word, like the eiffel tower:
When someone is clogging up the fast lane by going less than 20 mph over the limit. Typically, it's either a clueless geezer or someone engrossed in a dazzling cell phone discussion unaware of the constipation-like backup behind them. When the cork finally pops and the back up starts flowing, so do the middle fingers.
A freaking Fast Lane Cork made me late for work today.
