Ob-

/ob/ , pref. 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.
