I'm a little stuck... Click here to teach me more about this clue!

'irritating' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for abrasive that I've seen before include "Irritating in manner" , "harsh, rough in manner" , "Harsh; eg, emery" , "Rough, as sandpaper" , "Rough, irritating" .)

I've seen this clue in The Sun.
