Its a long story. I’m a co-founder of a Celestia group on DeviantART and we’re against all the negative memes and interpretations on Celestia. Based on what we’ve seen, people associate Trollestia with unfriendly, aggressive behavior and crude jokes/pranks that is usually meant to anger/frustrate/offend someone and/or hurt their feelings
I would agree it wasn’t cool of her. Mainly because Twilight would never let anyone - not even Discord - get off easy for mocking Celestia. Let alone laugh right in front of the pony in question when they’re clearly insulted.
I loved this scene! I instantly thought of “Trollestia” when I saw this, without any prompting from anyone else. I thought it was really funny when Sibsy tweeted “Trollestia”, too!
