Ba Dum Tsh
A drum sound you make when a joke is so weak it could barely light a match.
Ba Dum Tsh after my mom told a joke about her plants that was worse than watching grass grow.
My friend did the Ba Dum Tsh when I said, 'I’m so tired I could sleep for a month.'
The whole bar did the Ba Dum Tsh when the DJ told a joke that was louder than the music.
