Simultaneously freebooting someone else's video, claiming it for your own, while also humblebragging about its greatness.
Random Person 1: Man, my video about the American Empire only has 1.4 million views. How frustrating.
Random Person 2: 1.4 million views is awesome, and it's not even your video! It's CGP Grey's! Stop humblejacking, you chump.
