Very funny way of conveying your disdain to an actor (4)

Ross

I believe the answer is:

hoot

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

'very funny way' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'of conveying your disdain to an actor' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found within the answer.
The remaining letters 'hot' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
