I'm entering an amazing plus one - just came naturally (2,7)
I believe the answer is:
on impulse
'came naturally' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'i'm entering an amazing plus one' is the wordplay.
'entering' indicates putting letters inside.
'an amazing' is an anagram indicator.
'plus'+'one'='plusone'
'plusone' with letters rearranged gives 'onpulse'.
'im' going inside 'onpulse' is 'ON IMPULSE'.
'just' acts as a link.
Can you help me to learn more?
(Other definitions for on impulse that I've seen before include "without forethought" , "Spontaneously" , "Without premeditation or planning, perhaps buying" , "Without thinking" .)
