Squidiot

Those teammates in Splatoon that forget rainmaker checkpoints and just rush towards the goal before realizing you can't score more without getting the checkpoint and then die with the rainmaker in the enemy base, having scored basically nothing. Also commonly seen missing the basket in Clam Blitz, or just feeding their brains out. Whatever weapon they main, they don't know how to use it.

"This fucking squidiot got a 3/18 k/d, then picked up the rainmaker and fed with it in overtime"

BPN

Ballpoint Nouveau. The good Ballpoint Splatling kit in Splatoon 2

Mike: "You play Splatoon"

Sarah: "Yeah I main BPN"

Smells like fishsticks

An inside joke among my sister and her friends. No idea what it means.

My sister: "smells like fishsticks"

Me: "Why do you keep saying that"

My sister: "I won't tell you"
