Hokum - (noun) - 1. Foolish or untrue words or ideas. 2. Pretentious nonsense. 3. Message that seems to convey no meaning inserted into plays, novels, speeches etc. for humor or to evoke a response.
If a student adds to much hocum, when telling the teacher why he didn't do his homework, and arrived late to school,
he will likely not be pleased with the teacher's response!
Hokum is the one I found in the various dictionary listings (when I thought about the word). I think it may be personal preference or area usage. Like a lot of words we use. @Wes
However, "Hocm" (sounds like hocum when pronounced) is an anacronym for Hypertrophic Obstructive Cardiomyopathy. I thought that was interesting.
