When you are dumped by a significant other, only to find out that they are going to ask another person out right they dump you. Bonus points if it is a friend or their ex.
Oh damn, did you hear about Mandy and John? He dumped her to start dating his ex again. She got mesnicked.
You know when I stopped dating Bob for Julio? Well, I may have to mesnick
Julio, because Bob's looking hot right now.
