Slimepunk is a microgenre of music that emerged in the early 2010s within internet communities. It is characterized by an aesthetic dominated by slime-related pop culture references, ranging from The Toxic Avenger , Slime Time Live , Mountain Dew, and toxic waste.

Similar to Vaporwave and Seapunk , this aesthetic is an integral part of the genre and characterizes the artists who participate in the slimepunk movement. Slimepunk music often features heavy and distorted basslines and has largely emerged from a post-acid scene. Slimepunk artists tend to have a more aggressive or corrosive ethos reflected in their music. While there is no specific slimepunk sound, the aesthetic is a common unifying factor, and most slimepunk artists heavily feature sampling in their music.

"Slimepunk" was coined by Zombelle, one of the co-creators of the Seapunk aesthetic. It shares its early history with seapunk and many early slimepunk visuals shared on Tumblr were a combination of the two aesthetics. When asked in a 2012 interview about slimepunk's connection to seapunk, LE1F replied:

"Seapunk is far from over – #slimepunk came through #seapunk, and if anything, shows the strength of that movement. Slimepunk might be easier to embrace now, because it’s really up in the air… I had a convo IRL with Shan [Zombelle]... who started seapunk label Coral Records recently – they said, “It’s kind of nice to have a villain”.

Slimepunk was popular among teens and tweens of the internet that was very similar to Seapunk , but with more of a focus on slime. Slimepunk is often accompanied by black and other neon colors. Popular elements of Slimepunk include:

Slimepunk fashion often borrows from other aesthetics such as mallgoth and punk , but puts a slimier spin on the two. Neon green and black are often used in slimepunk fashion, as well as protective gear and rave gear.

One major aspect of the Slimepunk sound is deep and growling synth basslines, generally with dripping sound effects and/or Acid House influences. Some of the music approaches Acid-Tech in terms of sound but is distinct in its more atmospheric approach and loyalty to the overall Slimepunk themes of toxic waste and noxious sewer gas. Other Slimepunk music has none of these features but still exists within the movement. Slimepunk is based on aesthetic, and it is that aesthetic that ties all the different sounds together. Slimepunk the musical genre may not exist necessarily, but the movement definitely exists and musical representations of the core Slimepunk aesthetic can definitely be found.
