Huh? I mean, damn, lots of comments are wild. Just let people breathe a bit. Sometimes I'm also only realizing one or two things after I started talking. Sometimes even mid-sentence. And also, maybe for some people "huh" is just an instinctive reaction they burp out randomly. Also I go with the "what's huh after all" comment. Maybe they just abstracted the meaning of it in those simple letters. Maybe "huh" means a world to them
