Yes, stop with the flying kicks (ninja...i ) ^^ and start being nice, polite and considerate. (-:

it means not to harm you. cowboy...

As the others have said. It's a request from someone to be considerate and kind to them. Most people say it when they're new to a certain place like an internet forum, a game or a club. "Go easy on me" is a similar sentence used in such situations too. For example: (At Karate lessons) Person 1: "You ready?" Person 2: "Go easy on me, I'm new to this"

It's someone asking someone else to be nice towards him/her.

It means nice, gentle.
