hahaholic
A person who says haha so much it's like they're trying to scream through a kazoo. They do it online because they're too lazy to type real words.
He said haha to a comment that said 'I like pizza.' I said haha. The comment just said 'haha.'
She posted a video of a dog eating a sock and I said haha. Then I said haha again. Then I said haha a third time.
He texted me 'Hey' and I replied with 'haha.' Now he texts me with 'haha.'
