Sound effects of an Aerospace student

HUH: It's said with jaws down, eyes wide open, and a paralyzed tongue. It occurs mainly at the beginning of exams. However, it appears frequently in many classes: propulsion, Structural Dynamcis, and ALL Dr. Stearman's classes.

EH: Comes out of the throat, similar to the sound of choking on a grape. It roots back to the first Fluids class taught in the department. A student was eating a grape. When asked to solve the Navier-Stroke equation he choked on the grape. Trying to move the grape back up, the sound "eh, eh, eh" came out repeatedly. Now a day, it's the official sign of respectfully refuting a team mate's idea without making them cry.

Mhmm: No body knows the origin of this word. However, it is a daily afternoon happening in the aerospace classes taking place after lunch. It expresses students' utmost carelessness about the lecture topic. So careless they lack the desire to pretend to care. It's nap time.

BUH: The sound of a fist hitting flesh when one pounds on the chest. Back in the days when students where men with handlebar mustaches, when one asked "how did you do in the test?" One would hit on his chest with his fist and says, "I failed with bravery." Currently, it still said to answer the same question. "How was the test?" A single tear moving down their left cheek, the words choked down their throats, "BU... BU... BUH." (Stolen from the Knighthood of BUH)
