Last Lap Syndrome - or LSS, is the annoying fucking disease that plagues racing games everywhere. It usually occurs on the last lap of a long, hard, and/or very important race.
* Ramming into a tiny rose bush that completely totals your car 5 feet from the finish line.
* Leading 99 percent of the race only to be passed by the A.I. while he simultaneously receives a blow job from your girlfriend
and flips you off saying "SUCKA!"
* Head on collision with some stupid ass taxi that just had to pull out in front of you causing you to get in last.
* Leaving your sucky ass opponent completely totaled a mile away in his junker, only for him to recover as the best damn racer in the known world - then proceed to leave your slow ass rotting in the gutter while he blows passed you for the win.
