Whats Dc mean in Doja Cat music?

Doja Cats one line "he wanted them 3 rounds, DC had to come help." Whats DC mean? I can't find anything on Google that makes sense with the line. Thanks! "Isn't she in the 3 rounds already with who she is singing about, so how would she come help him if she is already there. Maybe I'm taking the lyrics to serious.
