You know these familiar faces; you incorporate them into your snarky group messages every day. That's right, we're talking — or, um, texting — about emoji. We love throwing those hilarious little symbols into typed-up conversations, but how about bringing them to real life? We've got you covered on all sorts of geeky Halloween costumes, but we're pretty pumped about this tech-savvy concept. Whether you're throwing an emoji party or need an ingenious costume for Halloween, these ideas will surely be crowd-pleasers. (Insert smiley face here.)
