Crossword Genius

Being upset, stand it no more -- protest! (13)

Ross

I believe the answer is:

demonstration

'protest' is the definition.
(I've seen this before)

'being upset stand it no more' is the wordplay.
'being upset' indicates an anagram.
'stand'+'it'+'no'+'more'='standitnomore'
'standitnomore' anagrammed gives 'DEMONSTRATION'.

(Other definitions for demonstration that I've seen before include "It's to voice protest" , "Protest meeting" , "Protest march/meeting" , "Display showing how something works" , "March; proof" .)

I've seen this clue in The Telegraph.
