Zim sat across from Gaz on an armchair, watching the girl play her game in silence. She seemed to sense his question despite the fact he hadn't said it.

"A 'boyfriend' or 'girlfriend' is someone you're dating." She informed without looking up. Zim tilted his head to the side in confusion.

"Dating? Like the giving of meats on the lurve day?" He asked as she continued her button pressing.

"That's part of it. It's basically someone you date, kiss, hug, hold hands with and sleep with." Zim nodded as Gaz looked up. He understood most of that. "Do you know what 'sex' is?" Zim tensed at the question. She obviously wasn't talking about 'sex' as in gender...

"Yes." He shifted uneasy under her gaze despite her eyes being closed. "My species mates similarly to yours." He didn't mention it being highly illegal. The act was hardly ever heard of and had only really been kept in their genes for emergencies. Otherwise, Irkens were cloned. Gaz smirked at him, eyes dropping back to her game.

"Well, if you both 'mate' then you're his 'boyfriend'." Zim paled at the thought. Mating with Dib! So what if the hyuman was tall, his hair oddly captivating and his eyes an odd hue Zim hadn't seen before any other hyuman... Zim shook his head, banishing the thoughts. Gaz had to be playing some mind games with him for Zim to even be thinking about mating with Dib. "Tell me who's bottom." She ordered and Zim stood, backing away from Gaz to return to the safety of the kitchen. Gaz scared him even more now.

"Zim?" He jumped at the sudden voice, spinning round to glare at Dib and feeling his cheeks flush as Gaz's words danced in his head. He glanced back over to the living room, sure he heard Gaz snickering. "Coming upstairs?" Zim huffed, squashing all unnecessary thoughts and emotions before looking back at the human. He wouldn't let confusion or embarrassment keep him from being Dib's friend. Gaz cackled loudly, probably completing her level and Zim found his feet already taking him up the stairs at Dib's side. She really, really scared him.
