A "Lancehole" (noun, plural "Lanceholes") is a cyclist who hogs the road and refuses to move over, regardless of whether or not he/she is actually meeting the listed speed limit. Many Lanceholes can be spotted donning their skin-tight, sponsorship-laden shirts and shorts.

An arrogant and unfriendly species, Lanceholes are fiercely aggressive assholes, often channeling their inner Lance Armstrong, hence "Lancehole". When threatened, Lanceholes commonly resort to threatening fist-shakes and comments, such as "share the road!”.
Passenger: "Hey man, you know you can speed up, right? You're doing 15mph in a 30mph zone."
Driver: "Sorry, I can't. This Lancehole in front of me won't move over."
Lancehole: "SHARE THE ROAD!"
