Guys in relationships I think it's important that you have a nuclear killshot tucked away in the back of your mind in the event that your girl ever goes off the reservation. Like if she's throwing shit and saying your peepee is small and being insane but you still love her and you know this is it, you need to either get her in line or say goodbye, you tell her "small peepee pairs nicely with small tits/fat cow/etc" whatever her insecurity is

Hopefully you never use it but if you do it's in a Flight 93 moment, it's tough because it takes millisecond thinking to make these decisions and if you're wrong you've torpedoed things forever
