Spots madcap (4)
I believe the answer is:
rash
I believe this is a double definition.
'spots' is the first definition.
(I've seen this before)
'madcap' is the second definition.
(thesaurus)
(Other definitions for rash that I've seen before include "Foolhardy about the skin infection" , "Careless" , "Overhasty - skin irritation" , "Hasty; skin disorder" , "Hotheaded" .)
