Hyperellipsecism

The condition in which one uses ellipses excessively.

Hyperellipsic: One who uses ellipses too frequently.

This is done by many who refuse to finish their thought or verbalize a sentence. Or for those who simply want to continue a conversation without having anything to contribute to it.

"So anyway..."
"Yes?"
"...iono..."
"Frankly, I think you suffer from hyperellipsecism."

"Uh..."
"Freaking hyperellipsic."
