Told fibs (4)
I believe the answer is:
lied
'told fibs' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lied that I've seen before include "Made up a story" , "Stated falsely" , "Told fibs - German song" , "was responsible for terminological inexactitude" , "Produced pork pie" .)
