Stand on business

To stand your ground, not let your guard down, not give in to pressure, not get distracted. Many women use it to refer to keeping your standards up and honoring their boundaries, often when feeling hormonal, lovesick, or temporarily attracted to someone.

“How tf am I supposed to stand on business with this man while I’m ovulating???”
“Girl, he apologized and wants a second chance! But I saw him making out with Susie last night, so I’m definitely standing on business.”
“Stand on business! Don’t be desperate!”
