Unlike famous meme clips tied to a single film or viral video, a squeaky trolley is a generic everyday sound effect, valued precisely because listeners recognise it instantly without needing any backstory. It circulates on soundboards alongside other short, practical effects that creators keep ready for comedy, vlogs and edits, where a familiar real-world noise can sell a scene faster than dialogue. Its continued use comes from that versatility: the same squeak can suggest age, neglect, effort or awkward timing, depending on the picture it is placed over.
