Norwegian Napalm
After eating a delicious but spicy Norwegian dish the man or woman, during sex, will excrete their steamy, sulfuric-like, liquidized fecal matter inside their partner's genitals causing a burning sensation for that person.
In order to impress his girlfriend Emily, Tom ate an entire bowl of seafood bisque before sex. Once Tom released his Norwegian Napalm in her vaginal crevice, Emily couldn't sit right for days.
