With it, in old slang (3)

Ross

I believe the answer is:

hep

'with it in old slang' is the definition.
(I've seen this in another clue)

This is all the clue.

(Another definition for hep that I've seen is " Knowing (jazz slang); rhymes with dance move".)

I've seen this clue in the King Feature Syndicate, the USA Today and The New York Times.
