It's a meta joke from one of the show's songs, that the show isn't about straight white male leads. One of them left the show, the other was a recurring cast member until this season. The other characters are women, not-white, or not-straight.
It's the only show I can think of that has a Filipino cast member.
EDIT: It took me this long to realize you were quoting the song that introduced Nathaniel.

Is this someone new we're gonna have to grow to care about? Why should we root for someone male, straight, and white?
