Shit Machine 

An alternative name for a dog; it doesn’t matter if it’s a pedigree or a mongrel, it comes from the old saying “a dog is a machine for turning food into dog and dog shit, but once it’s full grown it doesn’t produce dog anymore.” Strictly speaking it’s not the dogs’ fault but is due to irresponsible owners who fail to clean up after their animals.

I hope you’re going to clean up after your shit machine.

Machine Learning 

1. An Artificial Intelligence (AI) algorithm that proposes solutions to a problem after learning from several trial and error attempts.
2. A term that students use at hackathons to sound smart, especially when they actually have no idea what it means.

Example (from a 2011 Hackathon):
C++ Code:
int main()
{

cout<<"Enter your name";

cin >> name;

cout << "Hello, Brian!";
}
Brian: We used machine learning to greets the user, by learning their name.
*Brian won 4th place at the hackathon*
