Yeah, I think the problem is not about variable names but giving meaning to these abstract objects. Beginners often have difficulty understanding abstract concepts and specific (concrete) examples are helpful for them to learn. I think 'Funny words' alone will not be helpful, or even detrimental to beginners' understanding as they may be distracted by unrelated concepts (e.g. what do you mean by adding blues together in this example?).
