From the album Gemini Rights
Steve wants someone who's chemically unavailable, gets turned off when that becomes clear, then immediately tells other people to have standards he doesn't apply to himself. The contradiction sits there in plain view. He never names what he's running from, just what she's running from, like pointing at someone else's spiral lets him pretend his own isn't happening.
Baby, you got something in your nose / Sniffin' that K, did you feel the hole?
Steve frames ketamine use as escapism with surgical precision, the hole reference works literally (nostril, k-hole dissociation) and emotionally (void she's trying to fill). He's diagnosing her avoidance while setting up his own, which he won't name for another twelve lines.
Lookin' for a bitch 'cause I'm over boys / Would you be my girlfriend, baby?
He asks a drug-using person actively running from herself to be his girlfriend immediately after cataloging why she's a bad bet. The want happens at the same time as the diagnosis. He knows it's broken before he asks.
Something turned me off / Smoking made me, *cough*
The cough cuts him off mid-thought, like his body won't let him finish the sentence. He's about to blame the smoking for killing attraction, but the real turn-off is that she's as lost as he is. The line about wanting something secure lands different when you realize he just tried to build that security with someone running away.
If you had to stunt your shining for your lover, dump that fucker
This advice comes from someone who just asked an unavailable person to date him, got turned off by her unavailability, then framed it as sudden standards. He's telling her what he can't tell himself. Might be genuine wisdom. Might be projection dressed up as care.
Steve sees her void clearly because it's close enough to his own that he doesn't have to look at it directly. The ketamine, the new boyfriend, the toy line, all precise observations about someone running. But asking her to be his girlfriend while listing reasons she can't be present is its own kind of escape. He ends with advice he should take himself. Whether he knows that or not, the song doesn't say.
