circle theory 

Originates from Rutgers Camden. States that men are fixated on certain things because of their roundness. This encompasses, breasts, all manner of sport balls, bald heads, streetlights. The circle theory states that men in history and entertainment who want to dominate the world have this desire because it is round.

I guess you could prove I like tennis balls because of the circle theory.

Most common would be school/college/office/girlfriend/family circles . Your stuck on
