RTM
A more polite variant of RTFM.
Robert T. Morris Jr. , perpetrator of the great Internet worm of 1988 (see Great Worm, the); villain to many, naive hacker gone wrong to a few. Morris claimed that the worm that brought the Internet to its knees was a benign experiment that got out of control as the result of a coding error. After the storm of negative publicity that followed this blunder, Morris's username on ITS was hacked from RTM to RTFM.
