"Every Day I'm Shufflin'" is a catchphrase based on a line from the 2011 dance / pop single "Party Rock Anthem" by the American electronic hip hop duo LMFAO. The phrase has inspired the snowclone the "Everyday I'm X'in", which has frequently been used in image macro captions and animated GIFs. Remixes and parodies of the music video have been prevalent online since its YouTube debut in March of 2011.
The "Party Rock" shuffle is a loose interpretation of the Melbourne Shuffle, a rave and club dance that originated in the late 1980s in the underground rave music scene in Melbourne, Australia. The basic movements in the Shuffle consist of a fast heel-and-toe action with hand movements suitable for various types of electronic music.
Party Rock Anthem
On January 25th, 2011, the dance reached the American mainstream with "Party Rock Anthem," the first single released by LMFAO (an abbreviation for "Laughing My Fucking Ass Off") from their second album Sorry for Party Rocking. In January 2011, the duo held a contest looking for dancers all over the world to shuffle in their music video for the song. Intended as a parody of the 2002 horror film 28 Days Later, the music video is about people infected with a virus that urges them to start shuffling as soon as they hear the song. It was uploaded to YouTube on March 8th, 2011 and has received over 439 million views as of May 2012.
In addition, the music video held a Gold Recently Most Popular award and formerly held a Gold All Time Most Popular award. It also was #5 on the YouTube Music top 100 the week of November 29th, 2011. The song spent six weeks in the number 1 spot on the Billboard Hot 100 from July 16th to August 20th, before it was replaced by Katy Perry's "Last Friday Night."
Rick Ross: Everyday I'm Hustlin'
Although the line was popularized by the LMFAO song, “Everyday I’m Shufflin” is a parody of the “Everyday I’m Hustlin’” lyrics originally heard in the hip hop artist Rick Ross’ rap single “Hustlin”  from his 2006 album Port of Miami.
Following the launch of the music video in March 2011, LMFAO introduced a line of t-shirts with the slogan "Everyday I'm Shufflin." On April 15th, 2011, the first YTMND site titled "Everyday I'm Shufflin" was created, which featured a GIF from the 60s Spider-Man animated series.
The original music video, along with animated GIFs and image macros featuring the phrase, quickly gained traction through photo-sharing sites like Tumblr, Flickr and RedditPics. The first Urban Dictionary entry for the term appeared on July 31th, 2011. As of May 24th, 2012, an "Everyday I'm Shufflin'" Facebook page that has over 22,000 likes.
The line has also inspired an image macro series based on the phrasal template “Everyday I’m X’in”, wherein “X” is replaced with a verb related to the subject of the photo. On October 19th, 2011, Redditor jiehae17 submitted an animated GIF to the /r/funny subreddit, which featured the character Dumbledore from the Harry Potter fantasy film series dancing with the caption "Everyday I'm Dumblin'." The thread reached the front page and received over 2,000 up votes prior to being archived.
Many YouTube users have made video remixes combining "Party Rock Anthem" with footage from other sources. In particular, the 30 second long Shuffling section of the original LMFAO music video is often incorporated into other songs.
Search query volume for the term "everyday I'm shufflin" rose in April of 2011, shortly after LMFAO uploaded the music video. Search query volume for "Everyday I'm Hustlin" rose in early 2006.
