A driving
maneuver used by some drivers in
New England.
Quite difficult to explain, so I've made some helpful diagrams.
We have here one side of a 2-lane highway. The cars are moving from right to left. Car A is driving way too slow (by New England standards; probably 5 mph over the limit). Car B is set to pass Car A.

AAA

BBB
=======================
Here comes the
impatient Boston driver in Car C entering the scene at a
high rate of
speed. The driver sees that Car B is trying to pass, but Car B is going a little too slow for Car C's tastes. So he decides to try to beat the
guillotine.
-----------------------
AAA CCC
-----------------------
BBB
=======================
Car C will
accelerate in the rightmost
lane,
switching lanes at the
last possible moment,
cutting off Car B, and continue on its
way. Car C has sucessfully beat the
guillotine.
-----------------------
AAA
------CCC-------------
BBB
=======================
Now, this is a rather
tricky maneuver. If the driver of Car C judges the
speed of the cars wrong, or swtiches lanes to early, Car C will get
trapped in the
guillotine, with Car C
wedged inbetween Car A and Car B.

=======================
The
advanced Boston driver will perform this
manuever on single lane roads as well.
