Frampton's Butter? (3)

I believe the answer is:

ram

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

'butter?' is the definition.
(animal which butts)

'frampton's' is the wordplay.
'RAM' is hidden in amongst the letters.
But, I am not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for ram that I've seen before include "Aggressive sheep?" , "Thrust" , "needed for PC" , "force" , "barge" .)

I've seen this clue in The Sun.
