Meaning
Just the pink snout of a pig, two nostrils on a round nose, shown without the rest of the face. It literally stands for a pig’s nose and the snorting sound that goes with it.
It is a cute way to say oink, tease someone for snorting while laughing, or add a piggy touch to food posts and playful nicknames. Example: “I laughed so hard I snorted in the middle of the meeting 🐽”.
