the tuesday after a long weekend. Tonsday feels like a Monday but often is worse than a Monday, as everything you would have gotten done on Monday has now piled up onto the already large workload for Tuesday. Tonsday is the day where you pay for the enjoyable long weekend. There is always a ton of work to do on a Tonsday.
I hate tonsdays. Tonsday mourning hell
