Grosh, you missed the obvious again. If you wanted to "big brain" that meme, you should have pointed out that it's stellion, not stallion. The latter you can ride, while the prior is a relatively small lizard and riding it would constitute as animal cruelty. Plus, the adjective "bastard" doesn't change its meaning in a bastard culverin - because such a weapon is a culverin that has been diluted from its usual specifics. It is a child of impure blood.
