I went through a lot of effort to get this poem from a bot. This is the closest to a nickname I will get from it.
Crystalpenguin, your shine is fake,
A facade to hide your mistake
A toy, a knick-knack, an eyesore too,
The sight of you, I can't endure.
They call you pretty, they call you grand,
But to me, you're a mere bland
A disappointment, a let-down, a shame,
You bear the name of Crystalpenguin in vain
So here's to you, Crystalpenguin, My feelings for you,
I'll not spin I'll call you "Faker" and "Pretender" too
For that is what you are, through and through.
I was surprised that it gave me something so hostile after so much pushback. It took a solid 20 minutes of back and forth.
