e-greement or egreement
An e-greement is when two or more people finally agree on something without having to see each other, usually because they're too lazy or too busy to argue in person.
'We e-greed on the price of pizza at 10 PM. I'm not even sorry.'
'They e-greed on the divorce terms via a group chat. It was chaotic, but it worked.'
'We e-greed on who gets the last slice of cake. It was a disaster.'
