Car toilet clips circulate on user generated soundboards as part of a wider toilet humour trend online, alongside sounds like the fart meme sound that creators reuse for gross out jokes. The exact origin of this recording is not clear, but its short length and instant recognisability helped it spread through meme edits, gaming videos and short form comedy posts. It remains popular because toilet and vehicle noises are both familiar on their own, and combining them creates a simple, repeatable gag that needs no setup or explanation for new viewers.
