This is something I've seen a couple of instances of, and I'm not sure if it's actually a thing or just a couple of isolated incidents. That's why I wanted to appeal to the Troper hive-mind - are there other examples of this? This is a particular kind of parody song that combines a raucous hip-hop song about spring break with some other, completely unrelated subject. The humor comes from the juxtaposition of a brain dead party anthem with other, more serious subject matter.
- The Lonely Island has "Spring Break Anthem" (so, so NSFW) which is ostensibly a party song, but becomes gradually more and more about same-sex marriage.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
