Get the Jackhammermug. The act of taking a funny joke or meme and repeatedly making it less and less funny until it gets to the point where it no longer has any comedic value. The term comes from the word "jackhammer" which is a tool commonly used by construction workers to drill into the ground at a rapid pace. Jackhammering usually occurs with mainstream memes and jokes that become less funny when said mainstream starts to put their own twist on it. The joke loses all its luster after that.
"Dude, did you see youtube rewind?"
"Yeah dude, they were jackhammering the Shooting Stars meme! Remember when that used to be funny?"
"Yeah I know dude."
