What is meme?

Lost '''what is meme? (whats love) '''is a screamer video by YouTube user fanzorz1 on 2012.

The video starts was a song playing What Is Love. At the 16 second mark, the gif from the 1998 romance movie A Night at the Roxbury pops up. It replaced Chris Kattan's face with Epic Face, then it replaced Jim Carrey's face with Trollface, then it replaced Will Ferrell's face with Nyan Cat. However at 3:38 mark, a black screen pops up with a loud scream. After the screamer, a picture with the background color rainbow with Trollface on it and big white text saying: "PROBLEM OFFICER?" pops up with a vincent price laugh.
