Bossin up

To improve one’s circumstances in an impressive way. To move like a boss, making boss moves and leveling up, typically financially or professionally, but can mean personally (e.g. romantically or physically)

Did you see Kari’s new house? She’s really bossin up!

“Did know Kari got promoted to COO, opened her own shop, & been in the gym?”
“Forreal?? She really boss’d up!”

Stand on that

Stick with your decision and do not change your position now.

You said that you didn’t want to be with me anymore and acted like you didn’t care so you need to stand on that!
