I KEEP SCROLLING DOWN EVERYONE HAS A FENRARI ICON HNBGHH
Anyways. I have a very fullbodied laugh so I throw my head back. Or, giggle like a little girl. Which, I hardly giggle. Only two or three people can get me to that point 'cos I look down when I do, and usually blush when I'm laughing.
I have never noticed anything like that about myself, except for some hand motions here and there. Although it is moderately embarrassing that I usually think I've stopped laughing when something has stopped being funny, but for some reason I continue to laugh even though I am trying to stop. XD
But I didn't even have mic on >_>
Anyway, I might have been smiling or fake laughing, I sometimes don't hear well or bother to actually smile properly
Though how cool as it might be to look like a shark, it wouldn't be too good irl.
