Central Park troll 

Surprisingly not a troll, instead it's a person with an extremely cutesy and sachrine personality with a big sense of hope and optimistic glee, often to the point of making either realists or pessimists avoid that person (named after the title troll, Stanley, from a troll in central park)

Old man: Oh god! That little whippersnapper's a central park troll!
Younger lady: oh, don't be such a drama king!

Central Park troll 

A person who is unironically happy and upbeat almost anytime with a lot of optimism and hope. This type may also believe in following dreams. Sometimes used pejoratively by either realists or pessimists. (Named after Don bluth's film A Troll in Central Park, and specifically the title troll Stanley)

Normally: oh, my buddy is quite the central park troll. He can add a beam of sunshine over any bad day
Pejorative: that whippersnapper's a central park troll!
