Send-up exposed ludicrous naked figure (4)

Ross

I believe the answer is:

nude

'naked figure' is the definition.
(sculpture depicting a naked person)

I cannot understand how the remainder of the clue works.

(Other definitions for nude that I've seen before include "Wearing one's birthday suit" , "being out of the habit?" , "Completely unclothed" , "Classic art subject" , "revealing all" .)

I've seen this clue in The Independent.
