Liked chap’s name, so they say (3)

I believe the answer is:

dug

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

'liked' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for dug that I've seen before include "Delved; teat" , "Udder or teat" , "Appreciated" , "Excavated" , "Used a spade" .)

I've seen this clue in The Mirror.
