A grammatical point-of-view most commonly used in college dorm rooms, whereby the speaker (i) adopts the fictional persona of another party who exists in a separate context (e.g., a video game), and subsequently (ii) refers to himself or herself outside of such separate context, using the third-person point-of-view.
An example of proper usage of the Seventh Person form follows:
"Kong is going to the fridge to grab another beer. Does Yoshi need anything?"
"Kong is going to the fridge to grab another beer. Does Yoshi need anything?"
