no buts
Without excuses, compromises, or caveats of any kind. You need to be on time for school tomorrow morning—no buts about it!
no buts (about it)
1. Without a doubt or reservation. We're definitely going to lose our jobs after this merger, no buts about it.
2. Absolutely no excuses, discussion, or protestations (about something). I don't care how, but you make sure you're at your son's party tomorrow—no buts about it! No buts—just do as I tell you!
