Grenade Syndrome 

This is when a fat or unattractive looking women believes she is hot and can have any man she desires.

The grenade is the less attractive of the women in her group. They often get approched first by men. As this is often the way the group of men initiate conversation with the group of women. Thus giving the grenade a false sense of popularity and attractiveness level. Aka grenade syndrome.

My fat friend told me that she loves going out clubbing as she can get any man she wants. I dont want to tell her that she has grenade syndrome!
