However, you could use "prim" in a metaphorical sense, perhaps:
* "She prims her lips before delivering a cutting remark." (This implies she is carefully and deliberately making her expression appear more refined, though she's about to say something unrefined.)
It's important to note that this usage is quite unusual and might not be understood by everyone.
Would you like to try rephrasing your sentence using a more common verb? I can help with that! 😊
