This is an eight-second voice clip of someone repeating 'fla fla fla' in a teasing, sing-song way, like hands miming a mouth that will not stop talking. It feels silly and dismissive, the audio version of rolling your eyes at empty chatter, turning a long-winded rant into a joke instead of an argument.
