jumpu

Manga, especially from the shonen genre.

It's a reference to the anime Himouto! Umaru-chan, which in it self, references the Weekly Shōnen Jump (A popular manga magazine in Japan).
In the anime, Umaru refers to her maganize as "Shonen Jumpu".

Given that it's a light hearted comedy anime, folks using this term are usually talking/discussing manga in a very casual way.

The jumpu I ordered last week just arrived!

2Divorce

When you divorce your 2D waifu.

Usually meant as a more respectful and carefully ponderated action, as opposed to just switching best girl, as if they were some sort of object.

I recently 2Divorced Taiga. The flame was no longer there. I shall now endure No Nutting for the following week.
