Why Do Some People Get Hiccups More Than Others Why Do I Always Get Hiccups When I Talk To This Guy I Like?

Why do I always get hiccups when I talk to this guy I like? - why do some people get hiccups more than others

Ok so theres this guy I know for some time, and it seems that when I speak with him, I hiccup. Normally, when you say funny I can not stop laughing about something. This happens all the time and I feel embarrassed, but he laughs and thinks it's funny. The hiccups never at any other time. Only when I talk to him. Why on earth is wrong with me?
