the practice of preventing another driver from changing lanes. specifically, when a driver wants to change lanes while through-travelling, but finds himself stuck behind slower traffic, he may wish to pass the other vehicle. a lane blocker, however, will find a way to keep the passing driver stuck in postition, making it impossible for the passing driver to get around safely. usually this is a passive action, as opposed to on-ramp blocking or offramp blocking; often the offending driver is unaware of the faster car wanting to go past (often because the offender is talking on a cell phone.)
eric: come on man, just pass this truck! we're going to be late for the concert!
derrick: i can't pass him! the damned avalon in front of us is lane blocking me!
eric: flash your high-beams to get his attention!
derrick: i tried, but he's talking on his cell phone! must be more important than driving safely.
eric: what a dumbass bastard}!

If you live in between Virginia and New Jersey, you have heard of James Madison University's Block party. It is one of the funnest weed ends at J.M.U.
It is the first weekend before classes start so the students are ready to rage.

Michelle: I really don't want to meet with my adviser. I
need to get ready for Block party.
Courtney: Come on. There will be plenty of parties this year. Plus we can just wait and go at like 8.
Michelle: Are you joking? We have to be there before it gets dark. Think before you say stuff Court. Plus sun dresses look better in the sun

when you and a friend are tag teaming a girl, he has
her from behind, you got her mouth. Selfishly he shoots his load in her,
thus preventing you from using that road later.
