Even though unicode refers to it as an indicator of irony, referring to the ethology of communication, social mammals such as wolves, wild dogs, Lions, among others, used the inverted position to indicate submission, or at least, not aggression. In the case of humans, we are more complex, can mean the evolution of those prosocial manifestations, i.e., tenderness, affection and, in general, positive emotions
Emoticon or smiley is a neologism that comes from the English words quot; quot emotion; and quot; icon quot;. They are characters that represent a human face expressing some emotion. Also referred to as masks or gestural icons. If the face of the emoticon appears upside down, just turn it to straighten.
Specifically the face backwards is interpreted as quot; I'm amused because I see things in head quot; and possible profits would be: I say this jokingly; is just sarcasm; that crazy is this; the world upside down, etc. It implies that it is something that can not be taken seriously or that does not make me take it seriously
