What Does LUB Mean?

LUB means "Love." It is a also a sound made by the heart.


LUB is typically used as a slang word to replace the word "Love." LUB can be used as a direct replacement for "Love" with exactly the same meaning, in which case it is most likely to be used as an exaggerated expression of admiration or approval. For example:
  • "I LUB your hair!"
  • "I LUB it when that happens!"
However, it can also be used as an expression of devotion. When used in this way, LUB falls somewhere between saying that you really, really like someone and telling them that you actually "Love" them.

When used to mean "Love," LUB is sometimes typed as LUBB.
