1.
After driving along a 2 lane road, to pass the line of cars in front of you on the right when the road spreads out to 4 lanes at intersections.
I cosgroved 2 cars at the intersection.

I had a 3 cosgrove at the intersection (I passed 3 cars on the right).

I had a negative cosgrove at the intersection (cars passed me)

A dirty smelly fuck that is fat and lazy.
I'd rather hang out with a dead maggot covered rat in a trashcan than Cosgrove..

A fetish in which a man is turned on by watching videos of his own child birth.
Mom: Bob what are you watching?

Bob: I can't help it! I'm a cosgrove.
