I thought supercut[0] referred to an editing style of taking clips from different media, but with the same theme or meta-content, and string them together.

The style is discussed around the web (mostly annoyed people asking why other people do it). It seems to be called a jumpcut[1] though the definition for that doesn't really match what we're talking about.
