Want to win a nasty argument? Here’s what you have to say

We all fight with our baes, besties and family members occasionally, and it's those fights with the people who really know how to hurt you that sting the most. 

Whether it's a sly dig at a personality flaw you've been working on or an insecurity of yours that gets brought up, it's those horrible moments that really hurt.

'When [you're] in conflict, inevitably [you] will say something that hurts the other person using the inside information that you have on them or that they have on you,' relationship expert Hal Runkel told Business Insider.

'Everything in you wants to scream something right back at them: "Oh yeah? Well, you're starting to look like your mother!'"

According to the expert, it's not 'sorry' that will bring the argument to resolution, but 'ouch' instead.

When things are getting heated, it's at this point that you can take the 'ouch' phrase out of your arsenal and use it to your advantage. 

The relationship expert explained that the best phrase to use is: 

'Ouch. That one hurt. I don't know if you were meaning to hurt me.'

'I don't know if that's what you were going for; but that's what you did.'

It sounds like the updated version of 'I'm not mad, just disappointed,' and if 'ouch' instils fear into the hearts of our opponents the way that phrase used to in our teens, we're using it.
