We use the word ‘biddy’ to describe an old woman, usually in a derogatory way – ‘a nosy old biddy’, for example. Before I start getting cross about that (spoiler alert), here’s some etymology.
In the early 19th century, lots of Irish people were upping sticks and heading off to the US of A for a new life. Upper-class American families often paid for young women to make the trip, who’d then work as domestic servants to pay for their passage. In fact, this happened so often that these women came to be known as ‘biddies’, a shortening of ‘Bridget’, a popular Irish girls’ name. Which I think means it’s racist, as well as sexist. At some point it started being used to describe old ladies, which is where we find ourselves today.
(‘Biddy’ also seems to be a slang term for a chicken, although I don’t think that’s related to this meaning.)
Sadly, using a female name for a negative personality trait or as an insult still goes on today – the latest being ‘Karen’ for an entitled (usually) white woman who always runs to the manager to complain. There’s also a ‘Becky’, for a privileged, sheltered and unlikeable young woman (I believe the kids say ‘a basic bitch’). This one was made famous by Beyonce’s 2009 song ‘Sorry’ (‘Becky with the good hair’), but also appeared in Sir Mix-a-Lot’s 1992 hit ‘Baby Got Back’. In this case Becky was a lady with a big butt, which he liked very much and could not tell fibs about. ‘Stacy’ is another one – an unattractive woman who’s vain and rude, and only interested in sex (GOD FORBID). Worryingly, this one comes from incel culture, when men who live in their moms’ basements blame women everywhere for the fact that they’re celibate.
The only male equivalent I could find is a ‘Chad’. But predictably, this one actually has some positive connotations – a Chad is a sexually active Alpha male whose antics in the bedroom are never held against him. Then of course there’s the slew of other defamatory words for women with no male equivalent (or, if there is one, it’s often positive – like ‘spinster’ vs ‘bachelor’), most of which are related to sexuality. For example: cougar, gold-digger, bimbo, drama queen, slut, whore, nympho, tramp, slapper… I could go on. But I won’t, because it’s depressing.
