“The most basic emoticons are relatively consistent in form, but each of them can be transformed by being rotated (making them tiny ambigrams), with or a without hyphen (nose). There are also some possible variations to emoticons to get new definitions, like changing a character to express a new feeling, or slightly change the mood of the emoticon. For example 🙁 equals sad and :(( equals very sad or weeping. A blush can be expressed as :”> . Others include wink ;), a grin :D, smug :->, and tongue out 😛 for disgust or simply just to stick the tongue out for silliness, such as when blowing a raspberry. An often used combination is also <3 for a heart, and </3 for a broken heart. A representation of a cat face can be expressed like this: :3, along with a mustache emoticon
:-{ or :{D.
A broad grin is often shown with crinkled eyes to express further amusement; XD and the addition of further “D” letters can suggest laughter or extreme amusement e.g. XDDDD. There are hundreds of other variations including >:D for an evil grin or >:( for anger, which can be, again, used in reverse, for an unhappily angry face, in the shape of D:< . =K for vampire teeth, :s for grimface, and ;P can be used to denote a flirting or joking tone, or may be implying a second meaning in the sentence preceding it.[13]”
