F-factor - The F-factor is how much you like someone, but it's also how

The F-factor is how much you like someone, but it's also how much you're willing to punch them for.

I gave my friend a 7 because he's cool, but I would punch him for stealing my pizza.

My F-factor with my cousin is 10 because we fight a lot, but we still hang out.

My F-factor with my neighbor is 2 because he yells at me every morning and I hate it.
