I'll be neck
This means you're coming back, but you're doing it in the most lazy way possible. You're not even trying to be cool or dramatic, you're just coming back because you're too tired to do anything else.
I'll be neck, and I'm doing it because I'm too lazy to do anything else.
I'll be neck, and I'm not even going to bother to be cool about it.
I'll be neck, and I'm just coming back because I'm too tired to stay gone.
