The trouble with "what's the rawest lyric you know" is that without the sensory experience, or at least the knowledge of the sensory experience, of the lyric in the context of the music, they pretty much all — when put forward as TEH RAWEST — sound like tryhard 14yo bullshit
and nothing demonstrates that like going "OH YEAH PUSSIES WHAT ABOUT RAP, HERE'S SOMETHING WITH N-WORDS IN"
