Caramel's profile? What page was that shown again? And she could have said that meaning I'm happy to be in another generation of trouble raisers or she could remember Roger and his hat and noticed it on Luffy? It could be like a nostalgia happiness that being lumped in with them reminds her of her early days, idk.
When you solicit for a job, most of the time companies will spread vacancies describing which personality traits they prefer, which qualifications you need to have, what kind of education you should have followed etc. with other words a profile. The closer you conform with that profile, the higher your chances will be to be hired.
When the police searches for an unknown person, for example a murderer, they will most likely create a profile of the criminal based on the information they have so that they can channel their search into specific directions.
In this case it refers to Caramel's character profile derived from the little information we have of her. It's not much and obviously when we receive more info about her, the profile will most likely have to be edited. Logically however you are never or rarely going to see someone being profiled intentionally and explicitly in a chapter, it's something we do. In this case me and you can read about that in my previous comments, but if you want me to repeat myself:
Mother Caramel saved BM, a Yonkou, in some way and apparently this had a tremendous influence on her. No one however seems to know anything about what events transpired or the person that is named Caramel. This is kinda odd if all of this happened recently as from what kind of predicament would a Yonkou have to be saved and this without even her own children be knowledgeable about it? The most logical conclusion would be here that this happened a long time ago and considering the impact it had on her, you might even reason that this is what led to BM having the utopian dream of a multi-species family and why Caramel's picture has such a prominent place on her dining table. Normally you also don't refer to someone younger as you as "mother".
You can make a comparison here with the relationship between Luffy and Shanks as the latter saved Luffy when he was a kid and was a key influence on Luffy's dream of becoming the Pirate King. This would mean that Mother Caramel is quite old, like she experienced the rise and death of Gol D Roger and of course how this led to the Great Age of Piracy and it's kinda odd that she would identify herself with the current generation while having lived through all of that.
No Bonney really doesn't fit the profile as it stands now. To be honest her character has been quite underwhelming and her most prominent feat so far is being the sole female amongst the Supernova's. She also carries the questionable honor of being the first one to fall prey to the New World. Frankly the only thing that makes her character interesting, is the unknown nature of her relationship with the Marines and why she was so upset with the War of the Best.
