Fuck Twins are two people who have sex so much that they develop a twin-like connection in which they say the same things at the same time and can predict what the other person is going to say.
The other day I really wanted tacos for dinner and when I came home my boyfriend had made tacos without me even telling him that was what I was craving. We are such fuck twins!
