In his teenage years, IceJJFish attended Waubonsie Valley High School in Aurora, Illinois. Then in his twenties, IceJJFish gained popularity through social media sites, such as YouTube and Instagram. In December 2011, he uploaded his first video “Back That Ass Up”. It was followed by his first recorded song, “Higher than an Airplane” that same year. He uploaded two more videos the next year.

On November 25, 2013, IceJJFish released his debut single, “On the Floor”. He released its music video on February 6, 2014 via YouTube. The video was produced and promoted by San Antonio-based entertainment company ThatRaw.com. “On the Floor” marked his breakthrough success in his career; its video received over 10 million views within a month and currently has over 80 million views. His unique style of poorly crafted music garnered him several titles from media outlets that year, such as “internet idol” and “internet sensation”. It also led to his single “On the Floor” to be regarded as one of the worst songs of the 2010s.

In 2014, IceJJFish made a guest appearance in Odd Future’s Loiter Squad. In the episode he was included in, he created a song alongside Tyler, the Creator that was meant to troll hip hop. The song was titled “I Just Bought A Bugatti (I’m Happy)” and was applauded by critics for its humorous nature.

Later in 2015, IceJJFish would be featured in an episode of Nick Cannon’s Wild N’ Out. In the episode, he was involved in a rap competition with the show’s regulars.

In the second half of the 2010s, IceJJFish would go on to feud with artists such as Lil Yachty, accusing musicians like him of copying his sound. He would go on to release an EP titled LilJJFish as a result, with its cover featuring McLoyd mimicking Yachty’s appearance. IceJJFish then later went on to change his R&B sound to that of gospel, with the projects he released in 2019 reflecting that sound.
