1 definition by Turtle that cares about you

When you want to do something, but your mom says not to, or no.
You - "Can I go out with my friends tonight?"
Mom - "No, you have dishes to wash, and clothes to fold."
You - "But momm..."
Mom - "No buts"
You keep repeating the sentence until you magically disappear into dust due to Thanos' snap
Get the but momm... mug.
