COLLEGE PARK, MD — Two former University of Maryland men's basketball players are suing the creators of "Fortnite" for allegedly misappropriating the "Running Man Challenge" dance they popularized online.

In a lawsuit filed in Maryland, Jaylen Brantley and Jared Nickens claimed that Epic Games unfairly profited from their "Running Man Challenge" dance that went viral on social media in 2016. Brantley and Nickens — who were UMD students at the time — could be seen in the video showing off their dances moves and challenging people to dance along. The federal lawsuit claims "Fortnite" has infringed on the pair's copyrights by selling the dance emote, called "Running Man," as an in-game purchase. Brantley and Nickens are seeking upward of $20 million in damages.

Epic Games is the creator of "Fortnite," a wildly popular online games that lets players build forts and battle each other for the No. 1 spot. It's free to play the game. However, players can purchase customizable options for their avatars.

"(Epic Games) capitalized on the Running Man's dance popularity, particularly with its younger fans, by selling the dance as an in-game purchase in Fortnite, under the name 'Running Man,'

which players can buy to customize their avatars for use in the game. This dance was immediately recognized by players and media worldwide as the Running Man dance," the lawsuit read.

Despite Epic Games profiting "from its improper misappropriation of the Running Man" — as the lawsuit alleges — the UMD men's basketball team seemed excited that the dance was featured in "Fortnite."

The team's official Twitter account, @TerrapinHoops, posted a side-by-side comparison of the running man on Sept. 27, 2018:
