Fawning follower of a trapeze artist? (6-2)

Ross

I believe the answer is:

hanger-on

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

'fawning follower' is the definition.
'hanger on' can be an answer for 'follower' (thesaurus). I am unsure of the 'fawning' bit.

'of a trapeze artist?' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'a' could be 'an' and 'an' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for hanger-on that I've seen before include "A sycophant - he really clings" , "Sycophantic associate" , "Dependent - sycophantic follower" , "Persistent follower" , "Social leech" .)
