chawmp: n.

[University of Florida] 16 or 18 bits (half of a machine word). This term was used by FORTH hackers during the late 1970s/early 1980s; it is said to have been archaic then, and may now be obsolete. It was coined in revolt against the promiscuous use of ‘word’ for anything between 16 and 32 bits; ‘word’ has an additional special meaning for FORTH hacks that made the overloading intolerable. For similar reasons, /gaw bl/ (spelled ‘gawble’ or possibly ‘gawbul’) was in use as a term for 32 or 48 bits (presumably a full machine word, but our sources are unclear on this). These terms are more easily understood if one thinks of them as faithful phonetic spellings of ‘chomp’ and ‘gobble’ pronounced in a Florida or other Southern U.S. dialect. For general discussion of similar terms, see nybble.
