Kicked out of sack keeping excessively upset (6)
I believe the answer is:
booted
'kicked' is the definition.
(booting is a kind of kicking)
'sack keeping excessively upset' is the wordplay.
'sack' becomes 'bed' ('in the sack' means 'in bed').
'keeping' indicates putting letters inside.
'excessively' becomes 'too' ('too' can be a synonym of 'excessively').
'upset' shows that the letters should be reversed in order.
'too' in reverse letter order is 'oot'.
'bed' enclosing 'oot' is 'BOOTED'.
'out of' is the link.
(Other definitions for booted that I've seen before include "Kicked" , "wearing beetle-crushers" .)
