On a train last week, the young man opposite me ( he looked about twelve, but obviously had a full time job in advertising, as was confirmed by his full-volume conversation with a friend across the aisle) concluded his talk, not with "good bye", "see ya" or any of those variants, but a new one - at least new to me: "in a bit". I suppose it's equivalent to the American "later" as a conversation concluder. He confirmed the usage when he had a phone conversation, of which his half went:
"Hey, it's me. Listen can you bring my sandals to work? Wicked. Cool. OK, in a bit". Don't know what to make of it, except that my extreme old age is now confirmed by my getting irritated by things like this.
