Hey, Vsauce, Michael here! In the popular so-called “rock Sus” meme, Dwayne “The Rock” Johnson, the lead actor from the movie “Tooth Fairy 2”, thinks he’s listening to the beginning of the famous rock song “Under Pressure” released in 1981 by famous British rock band Queen formed in London in 1970 (at the time their line-up was Freddie Mercury (lead vocals, piano), Brian May (guitar, vocals), Roger Taylor (drums, vocals) and John Deacon (bass)) and famous English singer-songwriter David Robert Jones (08.01.1947 – 10.01.2016), known professionally as David Bowie. Dwayne nods his head, showing that he thinks “Under Pressure” is a good song, which it is. But then, the plot twist is revealed: the bassline is repeated again, but this time with an extra D3 (146.83 Hz) note (played on the 12th fret of the D string of a regular 4-string bass guitar) added at the beginning. This reveals that the song playing is actually not “Under Pressure”, but the famous hip hop song “Ice Ice Baby” released in 1990 by an American rapper Robert Matthew Van Winkle, professionally known as Vanilla Ice (born 31.10.1967), who sampled “Under Pressure” in his song and added that extra D3 note in the bassline. Dwayne either is confused because he wanted to listen to “Under Pressure” or doesn’t like hip hop (or maybe he doesn’t like Vanilla Ice for not paying royalties for sampling the bassline from “Under Pressure”(which is a very important part of the song) to Queen and David Bowie for a long time). He shows his emotions by raising one eyebrow and looking into the camera, as if asking “What is this \[song\]?”. The sound effect from Vine (an American short video hosting service released by Twitter (American microblogging website) on 24.01.2013 and later shut down on 17.01.2017), better known as “Vine boom sound effect” in the so-called “meme community” is added as Dwayne raises his eyebrow to amplify this dramatic situation, and a bass boost (an enhancement amplifying the low frequencies in a sound) is added to the sound effect to add even more dramatisation and a bit of hilariousness. If the bass boost is too strong, the low frequencies become distorted, which is clearly the case here (strong bass boost causing distortion is considered funny by some people in the “meme community”). The confused expression on Dwayne’s face makes this meme even funnier. I hope you learned something new today, and now understand why the “Rock Sus” meme is funny. Thanks for watching.
