Galoostic
A twerp who thinks he's hot stuff and spends all his time looking at rule34 instead of doing real stuff.
I asked him what he was doing. He said, 'Just browsing rule34.' I asked why. He said, 'Because it's cool.' I said, 'You're a galoostric.' He cried.
He tried to flirt with me using a heart emoji. I told him to go back to rule34 and die there.
He texted me a picture of a blurry face with a glitter filter. I called him a galoostric. He sent me a crying face emoji.
