1 definition by coolest people in the world

When spoken pronounced "oh-cheese". OCS stands for Only Child Syndrome. People with OCS are often only looking out for themselves. They disregard other people's plans, feelings, and ideas in favor of their own, and often change their minds, even after making "definite" plans. They're usually indecisive, as well as bipolar when it comes to relationships.
Person 1: "Hey, do you want to come to my house? We can get a ride."

OCS Sufferer: "No, I don't know, I want to be in NATURE right now.."

P1: "Um well....we could hang outside..."

OCS: "No no NO!...I don't know...I'm gonna go...maybe I'll come to your house later..."

P1: "But...we have a ride now!"

OCS: "Well I don't know what I want to do!!! I don't have allergies, so I'M ok here! Ugh!!!
Get the OCS mug.
