el Chupablanco means: He is a very white man with almost no skin color. His only goal in life, aside from pretending to fuck all women he meets, is to make drama in social settings.

It’s also important to mention that he likes glue, and is a bit of a nuisance in the Midwest. Because he is able to ravage entire towns in just a few hours with his fake fucking, he has earned the nickname Scourge.
