John Derbyshire, in reference to a child named in a recent Obama speech, blasts parents who invent names for their children:
I wish no offense at all to young Ty’Sheoma, but much offense to her damn fool parents, who saddled her with that absurd name. Making up a gibberish name and burdening your child with it is heinous. Sticking unnecessary apostrophes in there is beyond heinous. There should be fines, at the very least, for these parents.
Although he doesn't say it, the Derb is referring to what is almost exclusively an African American practice: creating a name out of sounds without any particular philological origin.
Although the results may sound odd (I have personally known two ladies named Niptheria and Retunga), I am sympathetic to the practice. If my identity group had been oppressed by a dominant culture for generations, and within recent memory, I would be inclined to reject the names of that culture on that basis alone -- even if it meant resorting to creating a name out of nothing. Better to have an invented culture of one's own than a historically-grounded culture associated with oppression.
