I know the new chapter is around the corner but bear with me and answer me this question. 
I don't think we've seen or heard his laugh yet, but I may be wrong. Anyway I think it we possible be something deep like Whitebeard's Gurararara like Mamomomomo. Of course it could be something silly sounding like other characters in the series have had as well like Shifafafa, Tunanana or (Goda forbid) KAAI DOH DOH DOH!
Please share your thoughts on what you think Kaidō's laugh sounds like!
