Cry of son the same after dropping ecstasy (6)
I believe the answer is:
squeal
'cry' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for squeal that I've seen before include "Make shrill cry like stuck pig" , "Make sound like as stuck pig" , "Shrill sound" , "Confess (under pressure?)" , "Spill the beans" .)
