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

'have a fling' is the definition.
(I've seen this in another clue)

Can you help me to learn more?

(Other definitions for throw that I've seen before include "Confuse - cast" , "Make a pot" , "Try to lose" , "Toss" , "Organise party" .)
