Image transcription: A screenshot of a Tweet by @Terror_Alarm, with images of Pope Francis and the transgender flag attached. The Tweet reads: "🇻🇦🏳️⚧️ His Holiness Pope Francis to finally allow #transgender Catholics to be baptized, the Vatican announced. It is a major step for trans inclusion, very big and good news for millions of Christians." Quote-tweeting this, @cungadero responds "he finally played his copy of undertale". End transcription.
For full context, there was an event where several YouTubers/Online personalities met the pope. I couldn't say the specific reason for doing so, but during their visit each of the groups presented a gift. In MatPats case he gave the Pope a copy of Undertale.
Then a lot of people started to clown on MatPat for giving the Pope a copy of Undertale. He made a response defending his gift choice, and honestly it wasn't that weird of a gift. It's just funny to me personally because the situation is so low stakes but became a meme because of MatPat's response.
