Siggi

A selfish opinionated and demanding person who uses someone for their own purposes. Someone who wants a lot but does not want to give anything. A person who demands something many times and way to often, but is not even aware of it.

Or a customer who is draining you out of time and good will, but doesn't want to pay a penny.

- "Hey bro, did she ask of help again, without even concidering paying you?"
- "Yeah man!"
- "Damn bro! Thats a classic Siggi."
