The song was inspired by the shirt that Dlamin was wearing when she was in bed making a beat. She explained to Genius
"A friend of mine sent a sample and I thought it was super cute. It was super happy and joyful and I was kind of done with making moody s--t. I didn't' feel like making like a love song or like a sex song again, 'cause I've been making that for like the last three weeks and I was like, 'F--k it, let me just f--k around.' And this shirt is ridiculous. The only thing is like, it was a distraction making this song. This top was a huge distraction for me. I would go to hit the keys on the keyboard and I'd have s--t in my way. But I'm just like, hitting the keys and I'm like, 'You know what, I'm just gonna make a song about cows.'"
Diamin added: "For the chorus. Bitch, I'm a cow.' I really just looked down at my shirt, looked at my sleeves and I went, 'S--t, bitch, I'm a cow' and I was like, alright, let me freak this and I put, 'Bitch I'm a cow', I wrote it all down."
