I'll be neck - It's like saying you're coming back, but you're being extra

It's like saying you're coming back, but you're being extra about it. You're not just coming back, you're coming back with a whole bunch of drama.

I'll be neck, and I'm bringing all my drama with me.

I'll be neck, and if you're not ready, I'm going to make you suffer.

I'll be neck, and you better be waiting for me or I'm gonna give you a headache.
