RTM: /R-T-M/ [Usenet: abbreviation for `Read The Manual'] 1.
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.
