Joint echoed to cheers from the audience (3,3)

I believe the answer is:

hip hip

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

'cheers from the audience' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'joint echoed' is the wordplay.
'joint' becomes 'hip' (part of body).
'echoed' says to double the letters (I've seen 'echo of' mean this).
'hip' doubled is 'HIP HIP'.

'to' acts as a link.

Can you help me to learn more?
