over-the-top melodrama, brought on by one's own stupid actions that is so painfully obnoxious everyone wants to injure you for acting that way. Named for Bella Swan of the Twilight series, who constantly puts herself in ridiculous situations and can't think herself out of a cardboard box.
"Do I love my boyfriend that I've been ridiculously in love with for over a year, or do I love the emotionally manipulative guy who is waiting in the wings that I think of as just a friend? Oh God, choices! I feel just like a Jane Austen character/Juliet!"
"I hate you and your belladrama so fucking much."
Similar to melodramatic, defined as "exaggerated and emotional or sentimental; sensational or sensationalized; over-dramatic" ......... but even *more* ridiculous, a la Bella Swan from the Twilight Saga by Stephenie Meyer regarding her entire relationship with nearly everyone in the world.
Him : OMG I ordered this with "some" pineapple and they only put a "little" pineapple ! I mean seriously did you not hear me tell them !! How many times do I have to tell them the difference between "some" and "little" !!! Do they not know who ... on and on.
You : Can you zip it! Quit being so belladramatic ... You're kind of a dick anyways.
