The act of laughing so much, uncontrollably that you don't stop for at least 5 minutes. No matter how hard you try to stop, you can't stop laughing. The tears in your eye, stomach hurting kind of laughing.
Jimmy watches a video about cats on YouTube and erupted into a lolfit. It took 3 weeks for him to stop laughing.
