A race taking place on a freeway or possibly any paved surface with 2 or more cars, where all contestants are to hold their speed at exactly 40 mph and at the end of the third honk accelerate to 140 mph at minimum.

Similar to 20, 30, 35, 50 and 60 rolls, all of such races have the standard of 100mph between start and end speeds.

Obviously the person in front wins if they complete the gap first, they stay out in front until all participants mutually shut cars down or all other participants let off early.

Get the 40 Roll mug.
the most epic, blessed, sexy, ridiculously and insanely best band ever created since the beginning of time. their songs will increase your penis size, cure you of cancer, be hailed until the end of time, make you stop listening to other music besides Crush 40, and basically turn your whole life around. most of their songs talk about adventure and living life to the fullest, such as "watch me fly" or "live and learn". if there's anything better than sex its definitely Crush 40.
holy shit, i just listened to one of Crush 40's songs, and my life is now complete. oh... and i also think my penis just increased size...
