Word:

# \begin

 (text, chat) \begin - The LaTeX command used with \end to delimit an environment within which the text is formatted in a certain way. E.g. \begintable...\endtable.Used humorously in writing to indicate a context or to remark on the surrounded text. For example:\beginflame Predicate logic is the only good programming language. Anyone who would use anything else is an idiot. Also, all computers should be tredecimal instead of binary. \endflameScribe users at CMU and elsewhere used to use @Begin/@End in an identical way (LaTeX was built to resemble Scribe). On Usenet, this construct would more frequently be rendered as "" and "" (a la HTML), or "#ifdef FLAME" and "#endif FLAME" (a la C preprocessor).
