A bad influence, who can be blamed for any bad behaviour that occurs.
They usually influence one about skipping school, doing drugs, and drinking alcohol on a semi-regular basis. Lying is also sometimes included in the 'bad influence' category while *deadbolt* is present.

They are native to Canada, but travel regularly.
"That kid is such a *deadbolt* to me."
