What's on your mug?

Mythical creature. It's like a horse with a seat on its head.

"Every girl wants a unicorn for her 16th birthday." "I'd say. Its ever better than a vibrator!"

Unicorn are mystical creatures which are attracted and could be captured only by a virgin. In VTuber terms, unicorns are mostly referring to fans (especially male) of female vtuber that who can't accept the behavior of their oshi having significant others or even interacting with any other males, hence keeping their oshi "pure". Compare to gachikoi, unicorns may not have a parasocial relationship with their oshi.
