The ultimate self-catering holiday? (3,4)
I believe the answer is:
ego trip
'the ultimate self-catering holiday?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'self-catering holiday?' is the wordplay.
I cannot really see how this works, but
'self' could be 'ego' (synonyms) and 'ego' is found in the answer.
'holiday?' could be 'trip' (I've seen this in another clue) and 'trip' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ego trip that I've seen before include "Self-important actions" , "Self-importance booster" , "totally selfish" , "Act done to increase one's self-importance" , "One's self-importance is boosted by it" .)
