1. Gifts that the recipient wouldn't dare use in public, or in front of another person—ever. An inflatable feline. Hmm. As tempting as this adorable kitten sounds, we really don't see anyone bragging about such a gift now, later, or anytime in-between. Plus, baby-talking to a fake pet is super embarrassing, even in the comfort of your own home. Rule #1: If you wouldn't be utterly excited to flaunt it around—or to use it in general—chances are your giftee won't be, either.

2. Random electronic gadgets. Nobody has time—or cares to—customize their toast. So, forget novelty toasters or any other electronic gadgets that A. will likely never get used, and B. have nothing to do with the giftee's interests.
