Oh man, this is terrible, but.. Back in the olden days, before call ID and such, when we were teenagers, partying, laughing, hanging, we would get out the phone book and look for couples only names, and depending on who picked up, male or female, either my girlfriend or myself would take the phone, and explain to the same sex person we were having an affair with their mate.
Like we couldnt go on with the secret any longer, and we wanted to be together, blah blah blah. 3/4's of the time, the people were like whatever, drunk retard kids. But that other 1/4 got completely out of control, like insano out of control.
It was absolutely hilarious, at the time. And we would fess up by the end, if it got too insane.
But believe me man, if you caught the jealous type on the phone, it would escalate super quick. I felt bad as we got a little older, like Damn I wonder if those people broke up or physically fought or whatever. Terrible terrible stuff.
Well, you asked, and I'm bored, so there you have it.
