'right to be a terrible dancer?' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'don't own' is the wordplay.
I cannot really see how this works, but
'own' could be 'have' (synonyms) and 'have' is found in the answer.
The remaining letters 'twoleftfeet' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
