A distortion is when something is changed or shown in a way that's not true. It can also refer to a noise or sound that's unpleasant and jarring.
We commonly use "distort" to talk about how information, like facts or images, are presented in a misleading way. For example, if someone makes a video where the shapes or colors look really weird just to make it more interesting, they're distorting reality for entertainment purposes. We also say that music can be distorted when it's played too loudly and gets fuzzy, making it hard to hear what's going on.
(transitive) To bring something out of shape, to misshape.
