When you read something hilarious on Reddit, and you have your pissed off sleeping girlfriend next to you, and you try not to laugh to not wake up the tyrannosaurus rex, it's like your body starts to build a laughter bomb in the bottom of your stomach, that you can no longer contain, eventually letting out bursts of loud gasping giggles while you try your hardest to keep it in. But the harder you try, the bigger it grows. The funnier it gets.
A rare condition experienced by some females during spates of intense laughter. Laughter legs are most commonly triggered by a hilarious joke. During an episode, the legs will wiggle, twitch, or squirm vigorously and uncontrollably, sometimes causing harm to the individual or to others in the vicinity of the legs. Further risks exist if the episode occurs while standing upright, causing the individual to thrust forward at high speeds in the direction they happen to be facing. There is no known cure, although studies indicate sadness is an effective treatment.
