Your friend offers you one more glass of wine on a Friday evening. You know you shouldn't but FIF (Fuck it, it's Friday).

This is a word used when someone else does something stupid. When the person does something stupid, you put your hand on his/her neck and slide it off fast, or if someone does something really stupid you give them an uber fifs, when you include some fingernail in your fifs and that makes it hurt a little.
