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

'fabricated' is the definition.
('make up' can be a synonym of 'fabricate')

I can't explain the remainder of the clue.

(Other definitions for made-up that I've seen before include "Applied cosmetics or healed breach" , "Put together as in parcel, or put differences aside to become friends again" , "Fictitious, invented" , "Fictitious, fabricated" , "Invented, untrue" .)

I've seen this clue in The Guardian.
