If you could permanently ban a word from general usage, which one would it be? Why?

In Norwegian the word I’m really getting tired of hearing is “serr” or as us grown ups say “seriously.” Gen Z says it constantly & repeatedly.

In American slang the word I’m getting very tired of hearing is “like.” I was told in college to stop using it as it made me some dumb when I’m not.

Another word I’m sick of hearing being used is “as if” making the adult talking to a child doubt what they’re saying. Their tone goes up because of ? & you hear it. No thanks!
