Bring trouble upon oneself when tackle catches pro (3,3,2)
I believe the answer is:
ask for it
'bring trouble upon oneself' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'when tackle catches pro' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'tackle' becomes 'kit' (both can mean gear or equipment).
'catches' means one lot of letters goes inside another.
'pro' becomes 'for' (I've seen this before).
'kit' enclosing 'for' is 'kforit'.
'as'+'kforit'='ASK FOR IT'
Can you help me to learn more?
(Other definitions for ask for it that I've seen before include "invite punishment" , "Court trouble" , "Request PCs, perhaps" , "invite criticism" , "court problems?" .)
