I Don't Follow or I Don't Follow Skyrim News is a running joke, mainly between Gassy and Danz, it means they don't know much about a subject or they're not an expert (i.e 'I Don't Follow Yogscast News'). As with most recurring phrases of this type, it's usually used sarcastically.
History
During a conversation about Minecraft and the Enderdragon in their Serenity Mine series, Danz admitted that he doesn't know much about the game Skyrim, evidently mixing up Skyrim dragons and the new Minecraft dragon. Danz quote was 'I don't follow Skyrim news" and it stuck. The Creatures have since used the joke in many situations and the title for videos like Danz' "I Don't Follow Moving Newz!!!" and Seamus' "P.O Box In Case You Don't Follow Creature News".
Trivia
- Danz's first shirt says 'I Don't Follow Skyrim Newz'.
