Your 'private square' is an invisible square that covers the top of your chest to just below your 'privates'. When someone (ie a rapist) moves to touch you inappropriately in this area, you must show them your 'Private Square'.

*Hold hand out in a stop sign*
STOP, don't touch me there!
*Do a 4 point motion of the square*
This is my private Square!
*Move arms rigidly up and down*
R. A. P. E!
*Point finger in a nagging motion*
Keep your hands away from me!
*Flail arms wildly as if you've just won the argument*
BITCH, go rape someone else!

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
