Top the Dog 

The act of holding one's own penis from the bottom, using the hand to simulate a bun, while another man masturbates on to the top of the receiving man's penis, to create the illusion of adding a topping to a hotdog.

Justin was feeling a tad bit bi-curious after his 6th shot of Jack, so he decided to ask Derek to "Top the dog."
