Bulublu is used when someone is so sad that the word "sad" is too much of an understatement.
Can aleso be used instead of words like weird, bad, horrible or annoying.
If two people are really close it can be used as a nickname.
OMG he cat died that is so blublu.
Awe you're so sweet you little blublu.
