Romeo cutting facial hair in pan (5)
I believe the answer is:
trash
'pan' is the definition.
(I know that pan can be written as trash)
'romeo cutting facial hair' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'facial hair' becomes 'tash' (I've seen this before).
'r' going into 'tash' is 'TRASH'.
'in' acts as a link.
(Other definitions for trash that I've seen before include "Worthless people; destroy (US slang)" , "Vandalise" , "Rubbish, refuse" , "Wreck; rubbish" , "pulp" .)
