Ellipsis Sine Wave 

An Ellipsis Sine Wave is a Sine Wave that is not fully connected; Ellipsis Sine Waves are also considered "Dotted Sine Waves" or "Dashed Sine Waves" they're like dotted lines except that it goes in a similar pattern as a sine wave. Real Ellipsis Sine Waves start large and then slowly decline exponentially slowing down. If you to the end of an infinitely large sine wave, at the end it would no longer be an Ellipsis Sine Wave.

In class, I drew an ellipsis sine wave so I wouldn't mistake it for the sine waves I had to solve for my homework.

Schrodinger's Wave 

When a person might be waving at either you or a person behind you. There is no way to know unless you turn around to check.

"Bro, I was stuck in a Schrodinger's Wave yesterday!"

"How so?"

"I saw this lady waving in my direction and I wasn't sure if she was referring to me or someone else. Turns out she was waving to someone behind me after I checked."

"Damn, that's rough bro. Must've felt awkward afterwards."
