In the hit song “Milly Rock,” 2 Milly raps that he’ll do the title dance move “on any block.” But when it comes to video game avatars doing a similar move called “Swipe It,” that’s where the rapper is drawing a line.

Variety reports that 2 Milly is suing Fortnite developers Epic Games, alleging they stole his “Milly Rock” moves for the popular game Fortnite. In the game, players can personalize their avatars with dance moves known as “emotes,” and 2 Milly says the “Swipe It” emote is a direct theft of his signature move.
