I think It depends on the context. Because a word is just a word and we fill it up with our culture, our ideas, our feelings, our moods. So, the same word could make people feel good or bad in a different context and pronounced by different people. I think this is crucial. As for me, I like that type of women, (also the one in shape) so you are on fire! And if I use the term I fill it up with a positive culture and point of view. (I read that ON fire means on the top and have a different meaning from you are fire....so I hope I used the right expression!!! Or the lady boss will come over to Italy to hit me!!!!!!) Noooo, I don't deserve that!!! So let me know if I made a mistake.
In the specific case, we all like you and the only letters which make me/us think of you are BLB: Beautiful Lady Boss!
By the way, you could add a B if you want (bus). I kidding
