Term originated from Jamaican patios. Used to describe people who are always up to mischief and adventure. Recently this term has been adopted by the independent clothing brand GNK which original stood for grizzle neck kids.
Term would be used in the following way: "See my boy Trilla yeah, he's been a grizzle neck from day"

Or

"I know my mans a straight grizzle neck but he ain't ever treated me like your fool of a boyfriend"

A turd/Blockage that is beyond the size and scope of comfortable passage through the anus. Usually passage is achieved through brute force and sheer determination. If "Grizzle Plug" is a regular occurrence consider water births or short shallow breaths. A possible change in diet may be required if "Grizzle Plug" persists.
