Associate socially with one's superiors (6)

I believe the answer is:

hobnob

(Other definitions for hobnob that I've seen before include "Associate familiarly" , "Socialise informally" , "Rub elbows with the biscuit?" , "Spend time chatting to a VIP?" , "Socialize, spend time with" .)

I've seen this clue in The Guardian.
