腦補 [nǎo bǔ]
v. Brain+enrich. Originating from Japanese anime, this Internet slang term means “to imagine and enrich the story wishfully [when reading novels or comics, watching TV series or movies, etc.]”. Originally the imagined scenes were often sexually explicit, but this Internet slang term has now been widely used as a trendy way of saying “imagine” or “visualize” in daily conversations. The visualized or imagined content is often pretty hilarious.
