@takashichea: I don't think their is a name for it. I think the show puts those scenes in their to show how quirky Akiho is. Alot of the characters on this show are pretty quirky. It might also be a characteristic on an otaku stereotype that show is trying to emulate. In Steins;Gate, the main characters were based on otaku sterotypes.
- Kaito - obsessed with video games
- Subaru - secretly cosplays/roleplays
- Junna - conspiracy theorist
- Frau - shut-in/ obsessed with the internet
I've seen all of the Steins;Gates episodes and I don't get why she does it either. It may not even mean anything at all. For example, in Steins;Gate, alot of the devices were given weird names like Future Gadget #8 "Phone Microwave (name subject to change)" and there wasn't really a reason for the name being what it is. At the same time, I could also be some obscure reference that we haven't picked up on. In previous series, they referenced 4chan memes like "All your base belong to me."
What we should do with the scene
If you're up to the task, we can add it to both the episodes and the character page.
