hag up
When a woman hits on a guy who’s into men, or a guy hits on a woman who’s into women. It’s like a hook-up, but it’s just friends, and it’s kind of gross.
She said, 'Hey, wanna grab coffee?' I said, 'Are you trying to hag up again?'
He asked me out, and I said, 'We’re just hagging up, not dating.'
My friend said, 'I just hagged up with my guy friend again.' I said, 'You’re so weird.'
