'for example love island vote regularly' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'overturned after early it glitches' is the wordplay.
'overturned' is an anagram indicator.
'after' means one lot of letters go next to another.
'glitches' becomes 'tv' (I can't explain this - if you can you should give a lot more credence to this answer).
'early' next to 'it' is 'earlyit'.
'earlyit' is an anagram of 'reality'.
'reality'+'tv'='REALITY TV'
