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

'erotic performances' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'upset friend skips' is the wordplay.
'upset' shows that the letters should be reversed in order.
'friend' becomes 'pal' (pal can mean a friend).
'skips' becomes 'dances' (I am not sure about this - if you are sure you should believe this answer much more).
'pal' in reverse letter order is 'lap'.
'lap'+'dances'='LAP DANCES'

Can you help me to learn more?
