This is slang for applying
large quantities of make-up to the face or body. It derives from the verb ‘pargeting’ which is to apply a decorative, waterproof plaster to a wall. The finished plaster is also known as pargeting and can be in a variety of colours. So if a
woman is piling stuff on her face,
eyebrows, eyes, lips, eyelashes or face, she is pargeting.
