Keino's contribution to a ski-party (3)

I believe the answer is:

kip

I'm a little stuck... Click here to teach me more about this clue!

'keino's' is the definition.
I can't tell whether this definition defines the answer.

'contribution to a ski-party' is the wordplay.
'contribution to' says the answer is hidden in the clue.
'KIP' is hidden within 'ski party'.

Can you help me to learn more?

(Other definitions for kip that I've seen before include "Short sleep" , "Sleep, nap (colloq.)" , "Slumber" , "Snooze" , "Nap (slang)" .)

I've seen this clue in the Evening Standard.
