look up any word, like lemonparty:
 
1.
When you're not sure wether to put hahaha or haha. You hope the person will take it either way. Many would think there is not a big difference between hahaha and haha but they are wrong. Haha is more of an unnecessary pause while hahaha signifies a joke was said that was actually worth a chuckle. Hahah is a good compromise for the indecisive.

Guy 2: Hahah, no way.
