Stinkchronicity 

After the term coined by Carl Jung for the phenomenon of an apparent pattern of coincidental events which, while lacking any causal relationship, bear a meaningful relationship to the observer.
Example traditional definition of synchronicity: You just wrote a protest folk song about "fracking" and a benevolent stranger sits next to you in coach, who is going to start an open mic cafe, in YOUR hometown, to build community around issues of climate change. Sooo--

The new word Stinkchroniciy means seemingly unrelated coincidences create a shitstorm of unfortunate events in rapid succession, making the observer feel completely victimized.

When the toilet tank cracked on the hottest day of the year, and the plumber's union went on strike, and your mother-in-law was due to be picked up at the train station in 5 minutes, and you go outside and see that all 4 tires have been vandalized with an ice pick, and just yesterday you tried to save money on your auto insurance and cancelled both comp and roadside assistance, WELL!, that's a whole lot of STINKCHRONICITY, alrighty, and why me, Lord, WHY ME...

Roger: "Hey Dano, check it out. I just broke wind while I was talking to that cop, but we were standing right by the sewer, so I was covered by stinkronicity"
