Stage performance barely entertaining the audience? (10)
I believe the answer is:
striptease
'stage performance' is the definition.
'striptease' can be an answer for 'performance' (I have seen 'Erotic performance' mean 'striptease' so perhaps 'performance' could also mean 'striptease'). I'm not sure about the 'stage' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for striptease that I've seen before include "Revelatory performance" , "performance taking off" , "that calls for gradual exposure?" , "in which all will be revealed" , "Form of entertainment" .)
