She met her match, I let her match
She lit her match, she let me smoke

from Chance The Rapper (Ft. Noname Gypsy) – Lost Lyrics on Rap Genius

Meaning

The parallels between relationships and drug use reoccur. As Chance and this girl fall away and she sees other people, he still gets to smoke weed with her, (and perhaps occasionally smash), borrowing the common idiom “meeting your match

“Let her match” means he told her to bring the same amount of weed he had so they could share.
