Drop a brick on toe: sit up if not broken (3,4,4,2,2)
I believe the answer is:
put ones foot in it
'drop a brick' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'on toe sit up if not broken' is the wordplay.
'broken' is an anagram indicator.
'on'+'toe'+'sit'+'up'+'if'+'not'='ontoesitupifnot'
'ontoesitupifnot' is an anagram of 'PUT ONES FOOT IN IT'.
Can you help me to learn more?
(Other definitions for put ones foot in it that I've seen before include "Commit a faux pas?" , "Make a tactless blunder (3,4,4,2,2)" , "usual way to use a sock" , "as one might with one's trainer" , "Bungle" .)
