The line comes from Shrek, the 2001 DreamWorks animated film where the ogre Shrek lives alone in his swamp and resents uninvited visitors. Voiced by Mike Myers, the character became a huge meme figure in the 2010s and 2020s, with his territorial quotes clipped for reaction videos and gaming edits. This short excerpt spread on soundboards and social media because it sums up possessiveness in a recognisable voice, letting creators make a joke about personal space without needing the full movie scene.
