1.
The art of hiding an erection while sitting and leaning one's upper torso at a 45 degree angle betwixt one's chest and lap. The owner of said erection then proceeds to arch their back in such a way that makes them appear to be sitting upright. This causes said erection to recede into the body causing a "turtle shell" effect.
