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!"
1.)A person with no friends who will most likely give up on life and bring a gun to school to shoot classmates as revenge. 2.)A person with no life who sits at home all day watching television, using the computer, playing video games, etc.
Haha, look at that kid eating lunch all by himself. I bet he is a schoolshooter
