Where you cum between a girl's tits or ass, press the tits or ass cheeks tightly together, then spread the tits or ass cheeks apart revealing a cum stain pattern similar to an ink blot or Rorschach test.
An Australian sexual practise. You sneak up on your sleeping girlfriend and holding the top and bottom of your ntusack with both hands, stretch your balls over her face, from her forehead down to her mouth. This way she wakes up to see an Anorexic Canetoad draped over her face
Shelia: "Jezus, what that fuck is that?!"
Bloke: "You've got an Anorexic Canetoad on your face, love"
