(Noun) A Shupenis is a meme obsessed pre-teen who can not do simple tasks without being hounded by his friends.

Signs of a Shupenis are being sent reposted Reddit and 4Chan posts in a group chat at 3am.

Someone can be a Shupenis if they have trouble letting go of a past lover, despite whether or not they actually talked to said lover. Shupeni' have a vast knowledge of the Metal gear lore, and deliver the dankest memes.
