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.
