I was just talking to a coworker, and had occasion to say (with charming self-deprecation) “Never heard of that, but then I’m not the hippest … uh … hepcat amongst the daddios.”
Yeah, that’s pretty much the look he gave me.
So what should I have said? How would you finish the sentence “Not the hippest ___”?
Cat on the street?
hipster in Starbucks?
paper shaker in the passion pit.
fream in the machine.
person in the world.
… no, check that. I am the hippest, for I am twickster, feared moderator of The Straight Dope Message Board. If I haven’t heard of it, it must not exist!
I’m not saying that wouldn’t get you a look too.
I probably would have said, “…hepcat, daddio.” Or something else entirely. Probably, “I’m not the hippest square but I am pretty hippy.”
“Never heard of that, but then I’m not the hippest breed of cat.”
I’m not the hippest pair of skinny jeans in the black plastic frames store.
OK, sorry. I got nothin’.
Potamus?
I gotta go with Greg.
Y’all would be astonished to learn that my status here doesn’t evoke interest, let alone respect, let alone awe, in anyone I know IRL.
Go figure.
They are beneath you, M’Lord, as maggots crawling in camel dung.
They waste the resources of intelligent people by breathing their air.
Win.
Are you trying to tell me that the SDMB is not part of real life? 'Cause I’ve got a postcard here that would disagree with that. 
Actually what you said made your point perfectly.
Thanks!
Uh …
hippest … uh … hepcat strikes me as redudant, i would have looked at you funny too.
I’d have probably just left it at, " I’m not the hippest."
What you said, would have made me laugh and nod in commiseration. And maybe snap my fingers.
And I tried so hard!
