Red Shelled 

When you're going down on a girl, and when you really start to enjoy it, she has her period. It's like being in first place in Mario kart, until someone uses a red shell.

It was going so good last night, until she red shelled me

red shilled 

Red shilled people are the tinfoil hats of the current generation.
The original meaning (red pilled) has its origins in The Matrix (Movie, 1999).
They don't listen to official sources (e.g. Media) but frequent forums that advertise consipracy theories and spread fear mongering (e.g. Alex Jones/ /pol/).
Since 'red pill' refers to the ultimate truth and nothing but the truth, red shilled users easily associate with posts/articles that claim to be red pilled or are advertised this way.
The irony is, that red shilled people suspect the media to be brainwashing them while in fact they are letting themselves be brainwashed by people that in a lot of cases just want to see the world burn (e.g. 4chan).
The red pill meme is also often used by Alt Right groups in order to distribute false or misleading information.

Phrases that might be used by a red shill:
'Women allow refugees to openly exploit our countries'
'Feminism is the cancer of the modern society'
'The cloud people are behind this'
'The government contaminates tap water in order to steralize males'

Example in a sentence:
"Holy fuck you are red shilled beyond recognition, corrupted doesn't even begin to describe it"
