They heard the CHOO CHOO of the train and ran up the steps with the stuff as quickly as can be, and found the best empty cabin where the previous students had stashed candy underneath the pillows.

"MMMMMM, this is good!" Peter had said in a muffled voice, as his mouth was full of chocolate frogs. Remus just smiled and Sirius laughed so hard everyone felt a crack in his rib. There was a pause, but as Sirius was ok they all got on. "You really like eating, don't you Peter?" James had jokingly asked. Peter just gave a thumbs up as he stashed his mouth with pumpkin.... whatever it was.

They all finished the snacks, and Sirius looked like he fattened up a bit, everyone including Sirius noticed, so they all laughed and laughed and laughed.

Soon there can a rather sophisticated boy, who had hair like Sirius but it was slick and smooth. James and Sirius were judgey about him, and Remus just stared. The boy had his nose up in the air and started to say, "You shouldn't be eating snacks on the train, it's not gentlemanly-like!"

James and Sirius said sorry, scowling. As they introduced themselves, the boy revealed his name was Severus. More like SNIVELLUS!!! Sirius thought.

The boy left, and everyone sighed a breath of relief. They all agreed his nickname would be Snivellus. And they decided to think of nicknames for themselves.

Sirius was Padfoot, James was Prongs, Remus was Moony, and Peter was Wormtail. They were all happy with these, and called eachother by those for the rest of the ride.
