Hmm, I assume this is a case of an experienced player helping a new one who is on the other team...reminds me of some servers on TF2 where people actually had fun teaching other new players about rocket jumping and sentry placement and so on.

Thanks for translating this. Any chance of translating the rest?

Also, I later found out that the Splattershot Jr. is called the Wakaba Shooter in Japanese, which explains the title.
