I think I spit lozenge

from Joey BADA$$ – Don't Quit Your Day Job (Lil B Diss) Lyrics on Rap Genius

Meaning

Double entendre: Lozenge i.e. cough drops/throat soothers. He spits fire so much that his throat is irritated and needs to be cooled down

And Lozenge

As in Joey spits diamonds; his raps are invaluable.
