A level of thickness that has transcended the physical three-dimensional world and goes into the fourth dimension. No current case is recorded of someone who has survived encounters with such a beings characteristic.
I heard a story once of a girl who was so thiqqq that when she went to school the students, staff, and the physical school itself were never seen again.
Unlike its betabrother "thiqqq", thiQQQ transcends beyond the discussion of the dimensional universe as we know it. No known encounters have been recorded though mathematical theory proves that such a level exists.
Cameron: "Bro how do we even know such a thickness as thiQQQ exists?"
Austin: "Quick mathsmy friend."
