Mexiblock
When driving on the highway with little to no traffic, and everyone in front of you is going the same speed so it is impossible to pass them. Coined in southern California.
That retard just moved from behind the semi and is going same speed. We're totally mexiblocked!

Getting blocked in a hall way or street by a group of very slow Mexicans.
I was late to class because I got mexiblocked.
