Dysonberry

A piece of dust or dirt that won't come off when you are emptying your Dyson cannister.

Normally the cannister empties out pretty easily, but every once and a while I have to shake a few times for the Dysonberry to fall off.

dysvocabulum

The phenomenon of using an incorrect word, spelled properly, when emailing, texting, chatting, or instant messaging. Sometimes, it is a homonym and sometimes just a word similar in letters and length. Often, this seems to be the result of fingers typing and brain thinking out of sync.

Examples of dysvocabulum include:

"I really blue that one!" (blew)

"Make sure you same your document." (save)

He must suffer from dysvocabulum (D.V.), because he just IMed me to, "Do it the write way."
