Need ideas for my Halloween Costume?

i have no idea but people keep calling me a cuz i always speak my mind and they ate that. so since they call me a . i made a condom hat looking thing. so im going as a giant . i think its helarious. but i have no idea what you should be. and vampires are stupid. so go as a slayer and make a statment. im not sure what a vampire slayer should look like i guess just look at the move charictors like blade and van helsing and make sumthing that looks like that i guess.
