Bum in rascal’s company (5)
I believe the answer is:
cadge
'bum' is the definition.
(both can mean to beg someone for something)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for cadge that I've seen before include "Sponge (money, etc)" , "Get by begging" , "Try to get (something) without paying" , "Scrounge (money, etc)" , "Try to borrow" .)
