Memes and jokes that actually influenced your way of thinking?
Hopefully with positive results.
A few years ago I frequented this Twitter community who would do livetweets of shows or visual novels. One day someone makes a joke video of someone livetweeting Gurren Lagann, getting to the first Giga Drill Break, and then pausing every 2 seconds to take a screenshot and tweet about how hype it is, completely ruining the momentum of the scene. That stuck with me for a long time so now when I watch shows, particularly Gundam, and want to talk about interesting or funny bits with others, I try to do it when the episode actually finishes or gets out of a scene
