Certain words or phrases become really popular. These words are picked up by many people, are overused, and sometimes misused to such an extent that the whole meaning of the word changes, or is even lost. I would describe these words as fads, because they become popular, but then (usually) disappear again.
- Like: This morning I was, like totally, late for work.
- Literally: If I do not get my phone back, I will literally die of boredom.
What is that phenomenon called? Is there a definition of what I just described?
Edit: After reading all the comments and responses I realized that my question was confusing. I was looking for a word that describes the phenomenon of (initially odd usages of) words being picked up and used by other people.
I gave the examples and stated what happens to these words to clarify what I meant.
