romped

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

'played' is the definition.
(romping is a kind of playing)

I don't understand how the rest of the clue works.

(Other definitions for romped that I've seen before include "Got home so easily" , "played with energy" , "cavorted" , "Red mop played happily" , "Played in lively way as children do" .)

I've seen this clue in The Globe and Mail.
