each other
When two guys (or girls) act like they’re gay for a moment, but only if they’re trying to be cool or if they’re in a fanfic.
They stared at each other for like five minutes. I said, 'You’re each other.'
They kissed in the fanfic. I said, 'That’s each other.'
They acted like they were gay for a moment. I said, 'That’s just each other.'
