Writing on a Laptop
These dongers are all typing something on a laptop computer. You can easily make an open laptop with ＼_. This is great for showing you are doing work or homework, or are just having fun browsing the web. This is definitely more applicable now than it was in the past.

Baka in Japanese means something like stupid or idiot. You hear anime characters yell this a lot. I’m not sure why these emotes are all typing baka but they wrote it so fancily with Greek letters. Maybe they are addressing a letter to something they think is an idiot?
