Chuck having a bit of fun (5)
I believe the answer is:
fling
'chuck' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fling that I've seen before include "Throw - short affair" , "Hurl" , "See 7" , "knees-up at 8 [HIGHLAND GAMES]" , "Toss" .)
