Lexiflex

To intentionally use complicated words in an attempt to seem intelligent. To flex one's lexicon, as it were.

Don't you muddy this up by lexiflexing. Speak plainly so you get your point across.

Hyperdeath

A death that kills every iteration of a being across all timelines- named so based on the idea that the fourth dimension is time, following the trend of a hypercube being a 4D cube. The term became popular after the release of the game Undertale, which features the character Asriel, who titles himself "The Absolute GOD of Hyperdeath."

Killing this iteration of you won't stop the threat you pose to innocents- I'll have to give you the release of hyperdeath.

Flaker

1. Someone who fails to honor commitments, either by making excuses or simply not showing up to the planned event.

2. Someone who regularly does cocaine, an illicit substance referred to by some as "flake."

It's been half an hour and Leo hasn't shown up- that fucking flaker.

You can't just snort the coke on my dinner table, you flaker!
