Public speaking is what teachers make kids do to embarrass them infront of their peers, so they get teased. Teachers think its fun to watch kids get nervous and stutter because then they can give them bad marks.
Teacher:"Class, you will be doing a speech(public speaking) next week on puberty"
Random kid: "AWESOME"
Teacher:"Sarah your up next"
Its where you go in front of a bunch of people and do a speech/powerpoint. All the while you worry whattheirthinking of you and just want to finish ur speech/ppt as soon as possible.
Even worse if you have social anxiety disorder.
I didn't do my speech in front of the class because I was too nervous; I lost a lot of points. Stupid fuckin public speaking.
