laughing in English is strange to me

so, in my country (Brazil) we laugh using "kkkkkkkk" or "kakakakakak" etc, and the classic "hahahaha" that is used in english, in my mind sounds like a villain laugh, and this is so strange to me, just want to share this difference

edit: i forgot to say that we brazilians only use "kkkkkkk" in social media, in real life we laugh using hahaha too
