I believe the answer is:
throw
This clue is a double definition.
'toss' is the first definition.
(I've seen this in another clue)
'chuck' is the second definition.
(I've seen this in another clue)
(Other definitions for throw that I've seen before include "shot-put event?" , "Chuck - confuse" , "Discard" , "pitch or > floor" , "Organise party" .)
