I've been receiving emails at work inquiring about registering our key fobs. This is slightly disturbing to me as I've always called it a key thob. An internet search for thob tells me I really mean fob, but if I force it to search for thob instead, it finds plenty of results (1.1 million for thob compared to 7.7 for fob).
Is thob considered incorrect? Is it recognized? Is it obsolete? Or are some people just making up words by calling it a thob?
