Periodt

The Wiggette version of "period" or "and that's final".

Used at the end of a sentence or argument when the speaker has a very high amount of (usually misplaced) confidence that they are in the right.

Also occasionally slapped onto the end of some really basic motivational quotes to put on Instagram or Snapchat to make it seem as if the poster is saying something incredibly revolutionary or meaningful when in fact they pulled the quote from a BuzzFeed list made back in 2016.

"Don’t let yesterday take up too much of today, periodt."
