Stick up or hold up (3)
I believe the answer is:
rob
I believe this is a double definition.
'stick up' is the first definition.
(I know that stick up can be written as rob)
'hold up' is the second definition.
(as in holding up a bank)
(Other definitions for rob that I've seen before include "Nick" , "shortened form of man's name" , "Hold up" , "Unlawfully take property from (someone)" , "Steal from (someone)" .)
