The inspiration for the song dates back to before Musgraves' previous album, Same Trailer Different Park, hit the shelves. "One day, we were out, somewhere outside of Nashville," Musgraves recalled during an appearance at Tin Pan South 2015. "It was last July. It was me, Shane, Josh (Osborne), Brandy and Luke Laird. We all traded off writing with different [people] … we'd draw names out of a hat."
"Here's what happened: We had started this song when we wrote 'Follow Your Arrow,'" McAnally added. "'[Mind your own biscuits]' was something we had said in another songwriting thing, and you brought it."
"We were like, 'That has to be a song, the whole idea,' and so we saved it," Musgraves continued. "I feel like it was Brandy, because she's like, if there's a puzzle piece missing in a song, she's just, like, infamous for [saying], 'You know, this may not work, but what about this?' And it always works. It's mind blowing. You're like, 'Oh, you just pulled this out of your little pocket there?'"
"[McAnally] said, 'Mind your own biscuits,' and [Clark] said, 'And life will be gravy,'" she added. "And I was like, 'I quit. Bye. Brandy, get out. You're too good.'"
"So a lot of people ask about the inspiration behind it," Musgraves concluded, "and all I have to say is, it's just good ol' plum country fun."
