Well, perhaps in this fan fiction, evil Dean and Sam are vampires who have been around for centuries. They giggle because they've developed a rather dark sense of humor over time. Their giggling often occurs when they plan elaborate schemes to outwit hunters. For example, they might leave false trails or set up traps for those who come after them. And as vampires, they have unique abilities that they use in these devious plans, like mind - controlling some humans to do their bidding while they stand back and giggle at the chaos they create.
A possible plot for the 'evil dean and sam vampires giggling fan fiction' could be that they are vampires who were experimented on by a powerful and evil force. The experiments gave them some strange powers along with their vampirism. They giggle because they find the world so different now. They form an alliance with other supernatural beings who are also outcasts. Together, they create a sort of underworld society where their giggling is a sign of their new - found freedom. However, they constantly have to deal with the threat of hunters and other vampires who don't approve of their unorthodox ways.
For Dean, you could develop his character as a vampire by emphasizing his protective instincts, but in a more vampiric way. He might protect his territory or his 'blood sources' aggressively.
