a creepy ass person who has too much time on their hands that stares and stalks people and makes it very obvious, they don't know they are called silent observer, no one likes them, they come on to girls that obviously arent interested in them
1: "Oh my gosh, watch out, theres silent observer again."
2: "Yeah I know, he always stares at my ass and once he took a picture of it."
