A super rude way to call someone a stupid dog kid. You yell it at guys who make you mad and want them to feel like a doorknob got kicked.
My friend spilled my coffee. I called him gaesaeki and threw the rest of my coffee at him.
I got stuck in traffic for an hour. I screamed gaesaeki at the guy who cut me off.
My brother took my last slice of pizza. I called him gaesaeki and sat in his spot.
