RTM

/RTM/ 1. [Usenet: abbreviation for Read The Manual ] Politer variant of
RTFM. 2. Robert Tappan Morris, perpetrator of the great Internet worm of
1988 (see Great Worm ); 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.
