Do Energy Sucking Vampires really exists? If so, how do they work?

Absolutely!! They suck out others energy by whining or being negative all the time or playing victim . They can suck out your soul if you are not careful

This one time a woman jumped out of the bushes with a gun and told me 'Give me some dick mothafucka'

I would categorize that person as a suckah vampire

My book is a bit about it. My version is someone latching onto your back, just piggybackriding you everywhere, adding weight.
