Loaded rifle, in case harassment starts (4)
I believe the answer is:
rich
'loaded' is the definition.
(I've seen this before)
'rifle in case harassment starts' is the wordplay.
'starts' says to take the initial letters.
The initial letters of 'rifle in case harassment' is 'RICH'.
(Other definitions for rich that I've seen before include "Possessing material wealth" , "Having lots of property" , "Full-bodied" , "Well-off" , "having much wealth" .)
