What Part Of No Don’t You Understand?
Meaning
This means that a no means no and no excuse will be entertained.
Origin
The California newspaper The Mountain Democrat in October 1988:
‘He wouldn’t take no for an answer,’ which gave meaning to the T-shirt Jim presented Carl printed with ‘What part of No don’t you understand?’
This phrase become popular after a song was written by Wayne Perry and Gerald Smith recorded by Lorrie Morgan:
What part of no don’t you understand?
To put it plain and simple
I’m not into one night stands
I’ll be glad to explain it
If it’s too hard to comprehend
So tell me what part of no
Don’t you understand?
