'Dy of the can'

Referring to one of Linguini Bros' written down lyrics. This basically means "candy," the "'dy" stands for the "dy" part that comes after can, and the "can'" part comes before the dy part.

This makes it so that the next line will rhyme, as this phrase was made for rap.
'Dy of the can' = candy

W4VEFORM: I won't hop in your van, it's not that I don't want the 'dy of the 'can, it's just that I know you don't be makin' bands.
Person in the van (kidnapper): 'Dy of the can'? What the fuck is that?
W4VEFORM: candy...
