What is “Tark” ?
Imagine the word trash.
Imagine a person who doesn’t speak english well using that word, but mispronouncing it.
This happened, and it evolved the word to “trach”. (where the ch is like “chimichanga”)
Imagine a bunch of people start using “trach” instead of “trash”.
Imagine this same bunch of people eventually ripping the word apart with even more gross mispronunciations.
Imagine the word evolved more, like this:
“trach” -> “terch” -> “tric” -> “trac” -> “tark”
So, tark is just a bunch of trash.
Also of note: A person can be a “tarker”, like if they won’t do what you want them to do so you call them that.
