Rockabilly types who have taken the tattooing very very far.So far, it has run up their necks. Usually with the stereotypical "swallows", "nauticalstars" or.. "your X's name"
When Social D was playing Street Scene this year, the

Man, His neck has so much shit on it!
As can be gathered from the expression, it indicates a state of intense anger and annoyance, so much so that the person making the threat is ready, willing and able to inflict physical pain and degradation upon the person who has annoyed them. While it may not literally result in the removal of the offenders head and defecating into the stump, it will usually result in physical violence and a humbling of the person who caused the offence.
The expression that is believed to have originated with the British Royal Navy. It gradually became used within all branches of the armed forces and later spread to the civilian organisations associated with them before obtaining wider usage.
To be in a situation that there is no way out of.
To no longer have any control over your own life.
To be totally surrounded by sheeple. (stupid people)
'I am totally neck deep in sheep shit over this baby thing I never should banged that silly bitch!"
