That sounds like "deaf" and has negative connotations, too. Same with "fun" (you're here to work, not goof off), "private" (you're not allowed to talk about genitalia at the workplace), "do" (a metaphor for sex, nsfw), "unix" (eunuchs), "bsd" (bondage, sadomasochism, domination), "curve" (whore in several languages), "fsck", "mount", "touch", "kill" (very negative connotations here)... and so on. I'm certain that nearly all one-syllable pronouncable words in English have some sort of "bad" meaning, but people are perfectly capable of keeping in mind what context they're used in, so we don't snicker each time we write "private int size;" in a class definition.
