an unfunny scumbag on youtube who is undeserving of his subsribers that blackmails other people, will make fun of someone's dead friend, will advertise his shitty discord server full of braindead children, and will extort you just to steal a meme

The act of being memeingful with the memes you make. Being memetastic is a trait that is really hard to achieve. Don't say you're memetastic if you make undank memes! Make memes great again.

Alexios: you're just a meme stealing WHORe!

Used as an adjective to describe an amazing meme, usually being referred to as a compliment to MLG trash. Often an adjective, it can be used as a noun by adding a 4, which would make it the Memetastic 4.
