laughitis

This is the common happening of someone laughing loudly and exuberantly (in other words scandelously) for a LONG period of time (without the use of laughing gas) when neither the person laughing or the observer(s) know what caused the laughing in the first place.

Person1)
He's been laughing for like 5 minutes .

Person2)
yep worse case of laughitis i've ever seen.
