Fool around for a quarter hour in the bathroom (6)
I believe the answer is:
loofah
'the bathroom' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'fool around for a quarter hour' is the wordplay.
'around' says the letters should be written in reverse.
'for' is a charade indicator (letters next to each other).
'quarter hour' becomes 'h' (abbreviation. I am not sure about the 'quarter' bit.).
'fool' back-to-front is 'loof'.
'loof'+'a'+'h'='LOOFAH'
'in' is the link.
Can you help me to learn more?
(Other definitions for loofah that I've seen before include "Kind of bathroom sponge for rubbing back" , "Rough sort of sponge" , "Bath sponge made from dried plant fibres" , "Bathroom sponge for washing back" , "something by bath?" .)
