A meemshkie, also known as a vagenis or teeny weeny, is simply a miniscule penis commonly found on blonde teenage girls. Most likely, they grow the meemshkie after seeking revenge towards an 'ex-boyfriend'. Girls who carry a meemshkie are usually stupid, bitchy, crazy, and/or somewhat ugly.
Meemshkies can also be pre-existing conditions, which grow throughout puberty.

Meeskacore is an aesthetic derived from the typical clothing, hairstyles, homeware and general image of a certain popular Instagram user and is named after her friendship group (Meeskas). It is centered somewhere between 2014 tumblr and cottagecore, with some unique characteristics.
That picture of hello kitty with bangs eating a strawberry in a tennis skirt is sooo meeskacore.
