1. An erection of the penis...
2. What happens to a girl's nipples when she gets cold or has water poured on her tits (like in a wet t-shirt contest)
3. A description of sex
1. "I stay hard throughout my Spanish class cause my teacher's so damn hot."
2. "My nipples are getting hard..."
3. "If you finger me good, I'll do you really hard."
