Turros

You had decided to go to the plaza with your friends. You got ready and left your house. After a few minutes, as you were walking along the sidewalk, some boys started shouting the following at you:

—OTAKU!!!—

That's what one of the boys in that group said while the others laughed; you didn't understand anything until you realized they were referring to you.

—What do they call you? ONII CHAN?—

Another of the boys said mockingly while that group laughed at you for your clothes which they considered strange.
