"Speed-Blocker"... similar in intenet to "C-Blocker" as someone who rides in the fast lanes of the highway going at or below the posted speed limit and MUCH below the speed everyone else is attempting to travel in that lane. Especially aggrivating when it is obvious the driver is purposely holding up traffic.
I was flying down I-95 to get to the game, but some S-Blocker was in the left lane holding everyone up and I missed the face-off and most of the first period !!!
