Attempt to grab bottom or hip (6)
I believe the answer is:
trendy
'hip' is the definition.
(I've seen this before)
'attempt to grab bottom' is the wordplay.
'attempt to' becomes 'try' (I've seen this in other clues).
'grab' means one lot of letters goes inside another.
'bottom' becomes 'end' (I've seen this in other clues).
'try' enclosing 'end' is 'TRENDY'.
'or' acts as a link.
(Other definitions for trendy that I've seen before include "Modish" , "Up to date, fashionable" , "all the rage" , "Informally, following the fashions" , "With-it" .)
