Terms of endearment

I just finished {A Spinster’s Guide to Seduction by Beatrix St. John} and the MMC persistently calling the FMC “pet” made me realise how badly a bad pet name (pun not intended!) can put me off. This author is a repeat offender as I also recently read {The Convenient Duke by Beatrix St. John} where the MMC calls the FMC “kitten” (made slightly less off putting for me because everyone else calls her Cat but still not great imo). Does anyone have any other hated pet names they’ve come across in HRs?
