weeb
What does weeb mean?
A Western anime fan whose obsession with Japan spills into their whole personality — sprinkling Japanese words into English, fawning over the culture, the works. Originally an insult, now often worn with pride.
Origin
Short for 'weeaboo', a term that originated on the message board 4chan around 2005 when a word filter swapped a different slur for the nonsense word 'weeaboo' from a Perry Bible Fellowship comic. It came to mock non-Japanese people obsessed with Japan.
