Jumpy Did You Know?

In Zero Escape, there is a Character named Akane, who is the protagonist's childhood best friend and love interest. The protagonist's name is Junpei. Early on, Joe gave Junpei the nickname "Jumpy", due to the two words sounding similar. However, a bit later in the game, it was actually revealed that Jumpy is indeed a canon nickname by Akane. Every now and then, Akane would randomly give out some encyclopedic information that made her sound like she was reading directly off of a Joepedia page. An example being knowing the exact crystallization temperature of glycerin, and facts about a fairly obscure phase of ice known as Ice-IX (Ice-9 in-game). Joe started mocking this all knowing character by saying "Jumpy did you know" before giving out random trivia every now and then on stream.
