Kyle In Chains 

Kyle In Chains, short K.I.C., is an M-rated Kyman (Kyle x Cartman, a popular fanon South Park ship) fanfiction that was written and published on FanFiction.Net by author DanniDinmont in 2008. It has 29 chapters containing 185k+ Words.
In this fanfic, protagonist Kyle Broflovski is a masochist, who is attracted to his frienemy Eric Cartman.

It is one of the most known fanfictions in the South Park fandom because of its absurd, partly disturbing and kinky plot, e.g. Cartman pretending to shove a goldfish up Kyles ass.

The opinions on Kyle In Chains are controversial.
A huge part of the fandom claims it to be child pornography, because the canon characters are about 10 years old. The aged up characters are about 16 years old, so the fanfiction sexualizes minors either way.

Another big part of the fandom semi-ironically stans Kyle in Chains, due to its popularity and the fact the fanfiction is actually written pretty good.

Some people just dislike the fanfiction because it is a Kyman fanfiction. These people most likely ship Style (Stan x Kyle).

South Park fans who have read K.I.C. often use the first sentence of the fanfiction “Change is a funny thing.” to refer to it.

After I pulled an all-nighter reading Kyle In Chains, I went to my local church to confess my sins.

schmegegge 

Yiddish slang word meaning bullshit, baloney, hogwash, nonsense, crock of shit or hot air.

I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
