Linus Van Pelt is the blanket carrying younger brother of Lucy in Charles M. Schulz's Peanuts comics, voiced in the animated films of the era. This scream comes from Snoopy Come Home, the 1972 animated Peanuts film where Charlie Brown travels to visit Snoopy's former owner. Clips from the classic Peanuts specials and films have circulated on soundboards for years because their clean, isolated vocal reactions are easy to reuse, and Linus having such an uncharacteristic outburst has kept this short yell popular for reaction edits and meme videos.
