Prezzie, sarnie & soz for sorry are all common parlance on Merseyside (or the bit of it where I grew up, anyway).
Hollibobs not so much. I used to share a house with a girl who said 'Shaftesbury Ave'. Not Avenue, just Ave. That was annoying.
I agree that Lil Man is utterly boaktastic - I have 2 friends on FB who, until the birth of their male children, appeared to be normal, functioning human beings. Now suddenly their feeds are full of LM, bubba and variations on hubby/hubster/hubs. These are professional women who until they went on maternity leave held down responsible, high-powered jobs. Perhaps it's just FB....
