Make up with mouthy type getting grief (8)
I believe the answer is:
lipstick
'make up' is the definition.
(lipsticking is a kind of making up)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for lipstick that I've seen before include "Colour applied to the mouth" , "Item of face makeup" , "Type of paint" , "Cosmetic item" , "Pick list, oddly, for the cosmetic" .)
