These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: S So HPKC
Sometimes, he will have some tropes that Your Mileage May Vary on. This is the place for those.
Troll: Not him, but one of his pictures of Trollax.
It's easy to tell which videos Seamus is indulging in this himself when he's filming himself, the Snorlax will be upside down. For videos he's taking seriously, the Snorlax will be right-side up.
In fact, one of his vlog videos, titled "I Don't Wear The Same Shirt Every Day" had him with five different shirts of the same design. It would seem like its one of these, but a quick pan over his stuff that he got revealed Snorlax was right-side up, meaning the video was serious.
He even has a series of videos called "Troll ______ Troll" where he plays games in a specific way to poke fun at commenters who tell him he's playing the game wrong.
