Trying to insert one of your testicles into your missus' vagina.

Note: Try to pop the smaller ball in first.
Note 2: Make sure your ball has been shaved first as it makes a smoother entry.
Note 3: Don't bring no cheese to the equation.
I was banging your ma the other night and tried to pop a ball in.

Balls deep wasn't good enough, went for scrotum deep.

See scrotum deep.
