D-Pain
D-Pain is when your dick is so happy it feels like it's about to burst. It can happen when you're drunk, you see a naked guy, or you just remembered you didn't do your homework.
D-Pain. I saw a naked guy in the grocery store.
D-Pain. I forgot my lunch and now my junk is confused.
D-Pain. My dog licked my face and now my dick is screaming.
