Songfacts®:

• This song is a sharp-tongued warning from Summer Walker to her lover's former flame. She keeps ringing her ex's phone and won't let him go. Walker tells the girl she is "ex for a reason" and has zero tolerance for her stubborn lingering.
• JT of the City Girls spits venom on her sassy guest verse. The Miami rapper threatens the lurking ex to step away, otherwise she's likely to get a slap.
• Summer Walker and JT wrote the song with:
  
  Los-Angeles based songwriter Nija Charles (Jason DeRulo's "Colors," Cardi B ("I Do" Chris Brown's "No Guidance").
  
  Producer Aubrey "Boobie" Robinson. His credits include 12 tracks from Walker's debut album Over It, including "I'll Kill You," "Playing Games" and "Come Thru."
  
  Summer Walker's boyfriend, London on da Track. The Atlanta beatmaker is her go-to collaborator.
  
  Atlanta producer Buddah Bless (Migos' "Supastars," Chris Brown's "Heat," Megan Thee Stallion's "Don't Stop").
  
  Veteran producer/songwriter Sean Garrett. His extensive resumé includes such smash hits as Usher's "Yeah!" and Chris Brown's "Run It!."
• Buddah Bless, Sean Garrett and Boobie's production is remarkably upbeat considering the menacing lyrical content.
• Nija Charles and Sean Garrett also supplied the background vocals.
• Summer Walker released the song as the lead single from Still Over It. The album explores the singer's tumultuous romance with London on da Track from her first day of recording on August 4, 2019 to October 7, 2021. During that period, they found love together, she gave birth to his child, and they broke up.
• This song finds Walker addressing one of London's past girlfriends, most likely Eboni Ivorii or Erica Racine. The singer had accused the two women of harassing her multiple times (Racine and Ivorii also had children with London).
