i used to go out with this girl who would get the hiccups all the time. it was awesome! but then she broke up with me... :( . anyway, while i was with her i found out how to give them to her. this method is also a great way to find out if a girl gets them often. okay guys, the first thing you do is get them aroused...kissing them lightly on the neck always works. that way their body becomes sensitive to touch. then you lightly stroke your fingers down her spine. blowing air on their spine works also. then she'll start to quiver and after a few minutes she'll start to get bad hiccups. when i used to do this to my ex, she would have the worst cases. but keep in mind this only works if the girl usually gets the hiccups in the first place. good luck guys!
