A mind stacker is a person who enjoys to confuse you and annoy you.
They will make your mind trip over its self (Hence the MIND - STACKER)
Many people will also call these people "Weird", "strange", "philosophical"
These people are closely related to Karl Pilkington and Amy Fiske
Amy F: What is the speed of darkness? If someone with a split personality threatens to commit suicide, is it a hostage situation? Why does someone believe you when you say there are four billion stars, but check when you say the paint is wet?
Whats the link between all these questions?
Randomer: Thats confusing... I don't know, your such a Mind-Stacker!
