Requiring lots of hands to rub in Vaseline all over the place (6-9)
I believe the answer is:
labour-intensive
'requiring lots of hands' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'to rub in vaseline all over the place' is the wordplay.
'all over the place' is an anagram indicator.
'to'+'rub'+'in'+'vaseline'='torubinvaseline'
'torubinvaseline' anagrammed gives 'LABOUR-INTENSIVE'.
Can you help me to learn more?
(Another definition for labour-intensive that I've seen is " Involving much work".)
