They didn't have school tomorrow, so Dib agreed. In the end, they were talking about the other's species. "What are those antennae for, anyway?" Zim looked up at the low hanging ends. "They are equivalent to human ears, I think. But they also show emotions. They twitch when Zim is confused, or nervous, and bend back when I am angry or frightened." Dib looked at them oddly, wondering why he never noticed the twitching before. Then he realized he never got nervous when they were kids. He was too confident for that.
Zim had very odd questions. "What are those hard, dark buttons on your chest? I noticed that the male swim-team had them. I am confused." Dib laughed. "Those are nipples. They aren't anything, really, just sensitive spots." Zim tilted his head at the thought of that. "Do you have sensitive spots?" "Of course, Dib-let," Zim looked at his antennae. "These are sensitive. Rubbing them calms me down." Dib noticed the left one twitch a little. "That would've been fucking helpful when we were younger." "Fu-king? Zim is confused." Dib laughed.
"That's called cussing, Zim. Fuck, bitch, shit…all used when you're angry or frustrated or something. Like when you say 'curses'. Humans replace it with cuss words." Zim tested the feel of cussing for a few moments. "Fuck…hmm…Fuck!" Dib laughed. Seeing that green skinned alien cussing was just too funny. "What is funny to Dib?" "It's just that you're so clueless to the humans, yet you've been here for about four years. It's funny." "Wait, I have a question." Zim said after a minute. "Hmm?" "Males talk about fucking. What do they mean?"
Dib blushed. "Do they have mating on your planet?" "Of course," "That's what they mean. Instead of saying mating, they say they fucked a girl, or boy." Dib thought of something. "Hey, do they have gays on you're home planet?" "What is that?" "Two guys that mate?" Zim blushed. "It is not usually practiced. We tend not to mate for pleasure." "Why?" The alien shrugged. "All males are expected to be soldiers. No time for pleasure. Invaders need no one." "Well, don't you get…you know…lonely?" Zim pondered this. "Invaders need no one." He insisted. Dib sighed.
"Do males mate here?" "Yeah, but they aren't supposed to…Nobody here likes gay guys." "Do you not like gay males?" Dib blushed, deciding to admit himself to the alien looking calmly at him. "Honestly? I'm gay." Zim looked shocked. "Odd. I always took you for someone who enjoyed females. I do not know whom I would prefer. I have never mated before." Dib asked his next question without thinking, and wished he hadn't as soon as the words left his lips. "You ever jacked off?" Zim gave his old, familiar look of skepticism; one ruby eye large while the other was half shut. "What is The Dib asking Zim?"
Dib laughed nervously. "You probably don't even have an organ for sex on the outside of your body." "What? You mean my…oh what do you call it on earth….erection?" Dib nearly fell over laughing. The alien was angry at first, but when he was informed what an erection really is, Zim blushed in embarrassment. "Fine, then. What do you call it?" "Penis. Or cock. Or dick." "Why so many names for one object?" Dib shrugged. "Well, yes. I have that. But I don't even want to know what 'jacking off' is." Dib secretly wondered what the aliens dick looked like, blaming it on his old love for paranormals.
The two talked for another few hours, but Zim eventually fell asleep, hugging his robot close. Dib fell asleep after reaching his own bed, not bothering to change out of his clothes.
