The racial slur of the day is Weeaboo.

It is used to refer to Whites.

Deep lore: During 2005, the imageboard 4chan experienced an increase in the usage of the derogatory slur "Wapanese". The moderators then used a word-filter, replacing every instance of Wapanese with “Weeaboo” which was a fabricated term originally coined by Nicholas Gurewitch in his Perry Bible Fellowship comic strip. Since then, paradoxically, the term was embraced and has become so popular as to transcend outside its indigenous sub-culture into mainstream.
