When a person, usually an adolescent female girl, writes haha before, in the middle, and after every statement made online regardless of whether or not its comical. Can also be substituted with LOL, and LMAO.
Person 1: Yo
Person 2: Haha, hey whatsup? Last night was so much fun hahaha. Your friends are pretty cool hahah.
Person 1: Yeah...Why are you saying haha?
Person 2: Idkkkk. Haha
Person 1: You need to shut up. You have haha syndrome.
