"You're a cutie, ay-ay-ay." It's a playful compliment often used in a party context.

Stand in casual clothes, and on the beat of "ay-ay-ay," jump into a "night out" or "glam" look.

Record a train or car ride at night with rain on the window, letting the "ay-ay-ay" part hit as you look away. For "Dvigat'sja" (Hype/Fashion)

Roughly translates to "Just run away... and don't look back." It captures the feeling of heartbreak and the desire to leave past memories behind.
