These smug emojis simply use a ~ like character for a mouth. Otherwise, they are pretty similar to the other faces in this category. Flat and closed eyes like ￣ are great for showing that these emoticons are smug. Many of them are also blushing or have a bead of sweat on their head.

These Japanese emoticons use a ェ for their smug looking mouths. Just like the other emotes in this category, they really don’t need to be all that complex. A smug look almost needs to be simple. They are so proud of themselves regardless so why bother?
