A meaning of a word is meaningless if nobody apart the writer
understands it. The purpose of code is 1) to communicate with the
computer, 2) to communicate with fellow programmer. The second point is
especially important if the code are written for pedantic purpose.
Teaching is largely one-way communication and often students that does
not understand about a slight point could not or would not communicate
their feelings because they think it is too silly. If the use of word is
criticized on a two-way communication channel (e.g. newsgroup), it
should raise a question of whether the word should be described first or
whether a synonym would be more suitable for the purpose. Most of these
do not apply on practical, non-pedantic purpose though, since in
non-pedantic settings you are expected to know and use the jargons
however (in)sensible they may be at first sight.

Nobody said code smell... linguistic smell is more appropriate.
