What does Morio-Kun Mean

Morio-kun is the name given to me by my Japanese teacher. Mori means forest, the 'O' is short for Otako, which means man. So my sensei added it together to make Morio, and the kun is like mr. or mrs. but is used between boys of or around the same age or who are peers. ex: a teenage kid name Bob would be called Bob-kun by his friend or a by a girl who is a classmate or friend. It looks like this in Japanese.
