Place it at the end of a procrastination setup, after a Game Show Buzzer Sound Button marks the failed excuse and before a Bruh Soundboard Button reacts to it immediately.
About this sound
This is a short Portuguese voice clip, lasting about four seconds, in which a speaker delivers the line 'Vão estudar, seus vagabundos!' in a loud, scolding tone. It feels blunt and mock-serious, like a teacher catching a room full of idlers, and its humour comes from how direct and over-the-top the scolding sounds.
