Thrown carelessly (6)
I believe the answer is:
tossed
'thrown carelessly' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tossed that I've seen before include "Threw in the air like salad or coin" , "Gored; (salad) dressed" , "'Threw, turned over (6)'" , "Lobbed" , "Thrown up in the air" .)
