KMFS 

Kill my fucking self. A more intense version of KMS Typically used when you're having an awful time, or if a unfavourable situation were to arise, so much that you want to die or are considering suicide. It doesn't necessarily mean you'll literally kill yourself, it can be used as a hyperbole.

1) I lost my job, I can't afford rent, my grandpa died recently, fuck it, I'm gonna KMFS.

2) If get woken up by my neighbours at 6am again on the weekend, I'll KMFS.
