(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.
"Did you fill out that College application yet?
No. Not yet, Elder Scrolls six just came out.
Stop being a fucking Shupenis and get to it."
