sexual fetish in wich a person gets aroused watching others vomiting.
Emetophilia
Not at all, unless they have emetophilia (which means that vomit makes them sexually aroused - vomit fetish). But no, most girls do NOT like puking on each other; just like most guys don't like puking on each other.
Metaphiliac, I may not have the spelling right! I just heard that tonight! I just can't find it on the net yet. My source may not be accurate, but I have found some related things on vomiting. Kevin
