No, to me the most annoying and irritating word is the inappropriate use of “like” as in “I was like...” We were like...” ad nauseam.
If you remomoved the word “like” from the English language, half of the people under the age of 25 in this country would be speechless.
It’s not even just “I was like” and “we were like.” They stick the word “like” randomly throughout a sentence. “And then, like, I said to him you’re, like, such a dweeb, like, really.”
