Obligatory. A piece of {netiquette} acknowledging that the author has
been straying from the newsgroup's charter topic. For example, if a
posting in alt.sex is a response to a part of someone else's posting
that has nothing particularly to do with sex, the author may append
`ObSex' (or `Obsex') and toss off a question or vignette about some
unusual erotic act. It is considered a sign of great {winnitude} when
one's Obs are more interesting than other people's whole postings.
