Xanya
"I thought that Cordelia was bad, but then Xander had to go and date my EX-GIRLFRIEND.
"Yes, that's right! Anyanka is my ex-girlfriend! Short, blonde, kinda annoying but very smart, very creative too...
"Oh, wait, I didn't date Anya, I dated Darla. Woops, my bad.
"So Anya is even worse than girlish figure tourist Xander! First, she lost her necklace because of her fail wish-granting, then she goes ahead and complains about it! Then she had a mid-life crisis and started to dye her hair blonde and brown and blonde again, and then she decided to marry Xander! Who is even worse than Anya, who is even worser.
"Also, she's scared of bunnies. She even sang a song about them. Um, rip-off of Percy Jackson's Grover much? (Even though PJO was written after Buffy. Shut up, me.)
"Then she started complaining about the wedding. And then Xander dumped her because of a fake future. Yep, that's right. A FAKE FUTURE. E.i., not real. Some crap about not wanting to be his father or something.
"So then I felt sorry for Anya, and wanted to castrate Xander. But then, I always wanted to do that. Hehehehe..."
*hums "Bunnies aren't just cute like everybody supposes!"* "What? It's a catchy song..."
