The act of tucking ones penis and balls between the legs so as to look like a woman.
I hear that cross-dressing queer Sal changed his name to Sally. I saw a picture of him dressed in women's lingerie and doing a penis tuck to hide his manhood.
The act of pushing the erect penis up towards the stomach and placing the end of the penis under the underwear elastic band, belt or other form of clothing which goes around the wast. The purpose is to hide the erection from view of others. Most commonly preformed before standing up.
I had a erection, so I used the old penis tuck. Problem solved
1. Waking up in the morning with your penis up your butt, normally with morning wood.
2. A karate move in which you drop kick a guy's penis from 3 feet in the air, sticking it up in his butt.
Ohhhhh man that Penistuck hurt soooooo much.
