I think quite a few of these sorts of expressions are 'in' jokes from film/TV etc but if you've never watched the shows then they just seem, well, a bit weird....
But that surely only works if the person you're habitually saying them to recognises the references, and/or finds them amusing/appropriate, otherwise you just have a cloth ear for your audience?
For instance, throwing around Shakespearean tags or Master and Commander jokes when both people know the plays/film/books is clearly fine, just as it's fine when DH and I, encountering cancelled flights, or a breakdown in rural France on a Sunday afternoon in August, will say to one another 'We've gone on holiday by mistake.'
But my father has the awful habit of just habitually saying phrases, over and over again, when neither he nor the recipient of his 'wit' knows the derivation or finds it funny -- he appears to have forgotten that he said exactly the same unfunny thing to the same unamused person an hour ago, or yesterday.
It's fairly clear to me that he's not neurotypical, and has at some point in his youth decided that this is how you communicate with other people, and has gone on doing it ever since because he thinks that's what you're supposed to do. He is as genuinely unable to see that the same truism from the Talmud or randomly breaking into a Flanders and Swann song, repeatedly, regardless of appropriateness or audience, is as maddening and boring as being the recipient, for the tenth time, of a twenty-minute (literally) account of his last visit to the dentist -- this has occasionally been told to complete strangers, too.
The other person I can think of who does this to a less agonising extent is a friend of mine who is also, I suspect, not NT. He's an attractive silver fox who has just become single in his early 50s, but I keep trying to hint that the language he habitually uses about himself will repel anyone - he's never in a rush he's 'bustling about', he's never sitting down, he's 'ensconced', and refers to sex as 'congress', always with an 'ahem' in front of it.
He also refers to making dinner and supervising homework for his children as 'doing the heavy lifting' (hence the divorce)...
