look up any word, like sex:
When people post videos of extremely bad quality on Youtube, commentators sometimes post a question asking, “Did you record this with a potato?” This questions how the video poster ever even thought that his video was youtube worthy; videos that receive this comment are often heavily pixellated, corrupted, excessively blurry, or constantly contain text that’s too small to see.

In these comments the word potato is often replaced with something else, for example calculator..
