Next generation Colt a bit of a rascal? (3,2,1,3)
I believe the answer is:
son of a gun
'a rascal?' is the definition.
(I've seen this before)
'next generation colt a bit of' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'bit' could be 'o' (resembles 0, a binary digit or bit) and 'o' is found in the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for son of a gun that I've seen before include "expression of mild annoyance" , "Rascal" , "Maybe Billy the Kid's issue" , "Rogue American" , "Jocular form of address (for Colt's relative?)" .)
