im a big fan of the theory that yiffy was a sort of 5D chess move from rose made as a sort of counter to dirk. its tied in with the "gloves are canon" theory i saw on tumblr a while back, that postulated the "hussie" in a threat sense was actually rose wearing gloves, and that the obama hologram in candy was potentially rose speaking through him.

the theory, if you're curious:

its also sort of tied in with my theory that yiffy is a rage player, as rage is an aspect that, when its in play, is trying to get you to stop caring about homestuck, which is sort of what yiffys entire existence is about. this observation about rage is shared by both tex talks (an old youtuber who made claspect analysis videos like a decade ago before seemingly vanishing off the face of the earth) and pgenpod (i don't remember what episode but i remember it was a thing mentioned there)
