Hackyhoe
A brainless, loudmouth, backstabbing friend who thinks sleeping with your ex is a trophy; she’s the kind of person who would trade your secrets for a free latte.
'He was single, I was single, we became a couple, and now you’re jealous.'
'I didn’t betray you, I just upgraded your relationship.'
'You’re not my best friend, you’re my ex’s ex’s ex.'
