Be like rebels? Me, rebellious? (8)
I believe the answer is:
resemble
'be like' is the definition.
(to resemble something is to be like it)
'rebels? me rebellious?' is the wordplay.
'rebellious?' indicates anagramming the letters (I've seen 'rebellious' mean this).
'rebels'+'me'='rebelsme'
'rebelsme' with letters rearranged gives 'RESEMBLE'.
(Other definitions for resemble that I've seen before include "favour" , "Look similar to" , "Look like (someone/something)" , "Possess some similarity to" , "Have similarities to" .)
