HK

A Japanese cat that has spawned many different product and clothing lines.

HK is an acronym that stands for "hugs" and "kisses," which is used to convey affection. It is often used when saying goodbye to represent the action of actually giving a hug and kiss.

You'll most likely see HK in text messages or online where character space is at a premium. You might also see H&K, which is the same as HK but with one more character.
