Dani

A Dani is someone who wants to be treated as a grown up, but is still very much a child, these people are very entitled and are always the victim in every situation. They complain about everything, has an excuse about why something wasn't done, or done correctly, or only 1/2 done. These people are drama filled and thrive on attention, whether good or bad.

I know I have a Dani,

She's such a Dani,
He's being very Dani like right now

FILF

Much like a MILF a FILF is a Friend I'd Like to F***

She's my bestfriend but she's still a FILF
