Context: This meme uses the classic One Piece ‘Blab Blab’ format. One guy is obsessed with an anime character named Yuri, while Luffy is a huge fan of cosmonaut Yuri Gagarin. They both shout ‘I LOVE YURI!!’ but they’re talking about totally different people. When they try to chat about it, they end up confused and eating in awkward silence. It’s a history meme because Gagarin was the first human in space, and the pun works in both directions.
