Gringosplaining
When an US citizen explains in detail characteristics of a culture, movement, country or race to a non-US citizen in a self-entitled way, always assuming their opinion is the most educated one. Most of the times, the opinions of gringosplainers are wrong.
"Look, I know you're from Argentina, but Argentinians aren't real latinos because they're white." "So you are gringosplaining me my own country? Andate a joder a la concha de tu madre."
