Girls fighting over boys

Hello gals, today I wanna know your opinion and reactions to these 2videos I'll be sharing with you. I'm making this post simply because it got me thinking what if I was one of the girls from these videos. What should I do? What is the right thing to do? What is the RIGHT and KICKASS thing to do to handle the situation?
I really need to know what you have to say, since I'm very interested on this topic~

Please watch and observe carefully

First vid is what I call "Japanese Style"


2nd vid is what I call "Filipina Style"


You might find the video funny at first, but I'm more ALARMED and PISSED OFF. In my opinion, situations shouldn't be handled like that and it looks fucking CHEAP and STUPID. But I can't totally defend my opinion, why? because I've never experienced it (and I don't ever wanna)I don't know how it feels to be cheated face to face or whatever.
But what if something similar to this happens to me? What should I do?
