Is it bad to post just one line from a college essay onto the Internet?

[The Internet]

I posted a sentence at random from one of my college essays on a Twitter account. It's just one random line, not even an intro or anything... But if a college admissions person somehow sees it, will they think my whole essay is plagiarism>

They are unlikely to think the whole essay is plagiarised due to you quoting yourself on twitter. It may be safer in the future to quote yourself AFTER you are marked or to paraphrase what you are trying to say.

However I don't see that you have done anything wrong.
