Swahealey 

"Mechanic-speak" mumbo-jumbo technical jargon used when discussing specs/repairs of vintage roadsters and sports cars. It's such a complicated and seemingly-unintelligible speech-pattern that it might as well be a foreign language to a non-mechanical-knowledgeable listener.

In "Back To The Future, Part 2", Marty protestingly says, "English, Doc!" when said wild-haired scientist is worriedly reciting his babbling Swahealey about how the DeLorean had been mis-used by Biff Tanned to majorly mess up the entire space-time continuum.

Swahealy

When someone is talking and you don't understand a thing they're saying. Jibberish.

"So if X is 34 and F is 5 that is (5x÷6f) x (3f x 9x)?"

"Whoah hold on there you're talking swahealy! Can you explain the question in a more simpler, more understandible way?"

Swaheely Fever

A very dangerous disease that gives you a fever up to 105F. Usually caught from swamps and wetlands, with mild to warm temperatures. Also, it can be worsened by damp, moldy environments.

There has been more than 237 confirmed cases since 1478, but has been eradicated since 1902.

Event though its a eradicated disease, there has been some controversy on rather if it really has been eradicated. More than 2,500 US citizens believe it still floats around in certain animals, such as reptiles.
