Here is an example of what I’m talking about:
Person 1: What’s up?
Man: Just at home haha
Hm? Excuse me? Hm, what? That you are at home is not funny. That you are at home is just a fact that is normal and fine. I understand you want to appear chill and don’t have the tools to appear chill in text so you have resorted to punctuating your statement with the onomatopoeia used for when something is funny but I’m going to have to give you this advice as a friend and confidant: don’t. 🙂
Here is another example:
Person 1: Did you have a good weekend?
Man: Yeah I went to the beach haha
