bear hug

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

'in wrestling' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?

'put up with the pressure' is the wordplay.
'put up with' becomes 'bear' (synonyms).
'the pressure' becomes 'hug' (I can't explain this - if you can you should believe this answer much more).
'bear'+'hug'='BEAR HUG'

Can you help me to learn more?

(Other definitions for bear hug that I've seen before include "embrace that's painful?" , "Wrestling hold" , "Rough tight embrace" , "Stifling embrace" , "Huge bra (anag.)" .)
