Hackyhoe
A loud, trash-talking friend who would rather be in a three-way than be in a normal relationship; she’s the type of person who would take your ex just to show you up; she has no brain and a mouth full of trash.
'He was single, I was single, we became a couple, and now you’re jealous.'
'You’re not my best friend, you’re my ex’s ex.'
'I didn’t betray you, I just upgraded your relationship.'
