Schoolhouse Fart
A squealing genre of flatulence commonly heard from one sitting down at an uncomfortable middle school desk, distinct in both sound and smell. A schoolhouse fart turns heads, not necessarily due to smell, but because of the scenario in which the toot was performed. Heads turn in disgusted disbelief. The best schoolhouse farts are undoubtedly expelled in a classroom setting - full of students, teachers, faculty, staff, and assignments.
"Ugh, did you hear Johnny rip ass during the middle of our Geometry lecture? Oh my, it was not just a toot, 'twas a schoolhouse fart!"
