Kicked for being too backward in bed (6)
I believe the answer is:
booted
'kicked' is the definition.
(booting is a kind of kicking)
'too backward in bed' is the wordplay.
'backward' says the letters should be written backwards.
'in' means one lot of letters goes inside another.
'too' back-to-front is 'oot'.
'oot' going inside 'bed' is 'BOOTED'.
'for being' acts as a link.
(Other definitions for booted that I've seen before include "Kicked" , "wearing beetle-crushers" .)
