"Apaci" is a word that comes from Turkey and it means someone who dances in a certain way. Imagine you're at a party and you hear some music that makes you want to dance. Now, if you start moving your arms around in a really exaggerated way and you start bouncing your legs up and down while you're dancing, that's what "apaci" means! It's a really fun way to dance and people in Turkey love doing it.
