Terrible thoughts that are repetitive and could come into your mind at any time without a warning. Also referred to as “Devil's Whispers”. A common symptom of OCD, but not always is. It easily convinces everyone around you that you’re going insane.
Someone 1: *Gets a panic attack*
Someone 2: “U good?”
Someone 1: “Nope. I had that same stupid intrusive thought for the 100th time today”
Someone 2: “Just be positive and your intrusive thoughts will go away”
As you can see, “Someone 2” has no idea what an intrusive thought is, and thinks it’s controllable.
A malady common to carbon-based life forms, cranio-rectal intrusion is also known as having your "head up your ass." As the size of any bureaucracy or institution grows, an exponential increase in the number of cases of "cranio-rectal intrusion" will also occur.

Something that forcibly imposes itself on you at a time when you don't want it.
Example: Facebook Messenger's extremely annoying popup notification that superimposes itself over everything else you are doing on your smart phone and has to be uninstalled in order to stop it.
I installed Facebook Messenger on my smart phone because I was forced into it with Zuckerberg's monopoly on social media and all, but I decided I would rather swallow glass than have to endure the annoying app -- and uninstalled it within 12 hours because it was so damn intrusive.
