They try to stop drag queen stuffing booty (8)
I believe the answer is:
spoilers
'they try to stop drag' is the definition.
The definition suggests an adverb but the answer is not.
'queen stuffing booty' is the wordplay.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'stuffing' means one lot of letters goes inside another.
'booty' becomes 'spoils' (both can mean the proceeds or prize from something).
'er' going inside 'spoils' is 'SPOILERS'.
Can you help me to learn more?
(Another definition for spoilers that I've seen is " leaked plot details".)
