Ostentatiously perform maybe leading to boos — what? (8)
I believe the answer is:
showboat
'ostentatiously perform' is the definition.
I can't tell whether this definition defines the answer.
'maybe leading to boos what?' is the wordplay.
'maybe' is an anagram indicator.
'leading to' says to put letters next to each other.
'boos' put after 'what' is 'whatboos'.
'whatboos' anagrammed gives 'SHOWBOAT'.
Can you help me to learn more?
(Other definitions for showboat that I've seen before include "What exhibitionists do" , "parade" , "Behave ostentatiously - river vessel" , "Floating theatre - musical" , "Kern Mississippi musical" .)
