A self-obsessed scene girl that makes videos on youtube and has a very large (and creepy) online audience.

everyone: mememolly.

Extremely cute girl on youtube. Makes weird videos about the most random things yet has tens of thousands of teenage subscribers who just watch her videos to stare at her boobs.
I only subscribed to mememolly's videos because she was pretty, not because her videos were any good.
