Psycho Study Bitch.
1) Generally a female biology major who is a crazy studier. Signs including typing notes on a laptop (typically a macbook pro), often with excessively loud keystrokes, copying pretty much word for word the lecture, then actually wants to compare notes 3 weeks prior to exams to ensure she didn't miss a single pronoun. Her typical diet requires a cup of coffee in in lecture to function. Excessively organized, the PSB's notes are often color coded, her text book is pretty much all highlighted, and she attends pretty much every extra study session/group possible, regardless of its actual usefulness. Ironically, despite this excessive level of preparation, the PSB often acquires mediocre grades, especially with regards to the effort exerted, and will inevitably begin to get gray hair and bald early from the excessive levels of stress she subjects herself to. Often feeling as though she has to prove herself as a woman in a "male dominated field", she will go to great lengths to ensure people realize her presence, be it via excessive questioning of the professor during lecture (often of rudimentary or offbase topics clearly intended solely for attention) or sending mass emails to the class for said sharing of notes and organization of study groups.
