Grief
From Second Life Wiki
To grief in Second Life means to cause great distress or to abuse another resident. To avoid "griefing" other residents, follow the Golden Rule of "treat others as you would like to be treated", unless you like to be pushed around, orbited, or called names, then you might just want to keep to yourself.
Read the CS and TOS and follow the rules or you could have an abuse report filed against you and possibly get a warning, suspension, or be banned from Second Life.
