I'm not sure there's that much intention. The students in my community college music classes use "random" as slang to describe things they don't understand. Students have used "random" to describe music by Arnold Schönberg (atonal, but highly structured), Milton Babbitt (total serialization), John Cage (OK, some of that really is stochastic), and W. A. Mozart (!! by an alto who hadn't learned her part).

"Random" also describes non-sequiturs that are then treated as hilarious jokes; Urban Dictionary has several examples. Anything is funny if it has a canned laugh track, right?
