"Mortal Man" by Kendrick Lamar is a song about loyalty and unity in times of crisis. The repeated line "When shit hit the fan, is you still a fan?" suggests that when things become difficult or uncomfortable, true commitment to a cause or a community is put to the test.

The reference to the "Hard R in Hangman" is a nod to the controversial use of racial slurs in popular culture. The lyric asks listeners if they would still support an artist who uses such language, or if they would turn their back on that artist. This raises questions about accountability and responsibility in the entertainment industry, as well as the morality of consuming media that perpetuates harmful ideas.

Lamar's use of the word "nigga" throughout the song also highlights the struggle that Black artists face as they navigate the complexities of language and cultural identity. The final lyric, "When shit hit the fan, is you still a fan?", can be interpreted as a call to action for listeners to remain committed to social justice and equality even when faced with adversity. In summary, "Mortal Man" is a powerful commentary on the importance of loyalty, accountability, and solidarity in the face of social and political upheaval.
