You're going to look pretty funny trying to eat corn on the cob with no fuckin' teeth!

Our reading
An editorial interpretation.
The speaker threatens the listener through an image of trying to eat corn without teeth. The imagined practical difficulty makes the violence sound both menacing and absurd. Rather than describing the threatened blow directly, the line dwells on an awkward consequence and turns it into a dark joke.
