A girl named Mia was dared by her siblings to try a new and very spicy food. Mia was not used to eating spicy things at all. However, she was determined to take on the dare. When she took the first bite, her mouth felt like it was on fire. But she managed to finish the whole plate. After that, she actually started to develop a taste for mildly spicy foods as she realized that she could handle more heat than she thought.
In a non - vulgar context, it might be a story where the girl is begging the guy to take on a responsibility or engage in an activity that he is reluctant to do. For example, it could be something like asking him to clean up a really messy area that he has been avoiding, and the phrase is used in a very hyperbolic or metaphorical way.
