Another one is the verb "perceive" i.e. "don't perceive me" "I am perceiving" "I am being percieved." That's something that feels very specific to tumblr parlance.

There's the thing where people on tumblr have an emotional reaction to something and instead of, or in addition to telling you how they feel about it using emotion words, they will narrate a fictional action in the present progressive tense. "I am gnawing at the bars of my enclosure "I am kissing you on the mouth" "you are going into the soup" "you are getting all of the awards"

I once saw someone use that response format in ... I think it was a restaurant review, or a doordash review, or something like that. It was very unexpected seeing it outside of a tumblr post.

sadly my project is lost due to the website being wiped from the university database after graduation and my then laptop having a major hardware failure. backup your backups people! but the crux of the entire module was that the internet is full of communities using language not only as jargon for specific purpose but also to signal membership in said community. I even wrote a bit about non capitalisation and punctuation useage as a visual cue on tumblr and how including information in the reblog body or the tags indicated different levels of importance or intimacy of thought
