Why do some pilots misuse (troll) the GUARD frequency? When flying I almost always monitor GUARD, VHF 121.5 on my second communications radio. It's almost a daily occurrence that I hear someone transmit the words "work work work" or a long, theatrical "GUUARRDDD!" as a response to someone calling for a ramp taxi clearance on the wrong frequency.

It is interesting that these particular responses are so prevalent.

Has anyone studied this misuse of the guard frequency to determine if there might be a cultural source?

At least in my experience with the last decade of aviation, there hasn't until fairly recently but such common use of the guard frequency for communications which aren't pertinent to its purpose. Has the FAA taken any actions on pilots for misusing the guard frequency in the way mentioned in the first paragraph?
Every field has its bottom 2%, and some of ours regularly self-identify as such on 121.5. 

Sigh.

The "work work work" refers to this video (start about 2:55 for the relevant section).
