DEC's engineers nearly got a PDP-11 assembler that used the

SEX mnemonic out the door at one time, but (for once)
marketing wasn't asleep and forced a change. That wasn't the last
time this happened, either. The author of "The Intel 8086
Primer", who was one of the original designers of the 8086, noted
that there was originally a SEX instruction on that
processor, too. He says that Intel management got cold feet and
decreed that it be changed, and thus the instruction was renamed
CBW and CWD (depending on what was being extended).
Amusingly, the Intel 8048 (the microcontroller used in IBM PC
keyboards) is also missing straight SEX but has logical-or
and logical-and instructions ORL and ANL.

The Motorola 6809, used in the Radio Shack Color Computer and in
U.K.'s `Dragon 32' personal computer, actually had an official
SEX instruction; the 6502 in the Apple II with which it
competed did not. British hackers thought this made perfect mythic
sense; after all, it was commonly observed, you could (on some
theoretical level) have sex with a dragon, but you can't have sex
with an apple.
