One Man Human Centipede 

A trick that surgeons use on patients who are being disrepectful to them or their staff. The procedure involves attaching penis to anus.

One-hand tuck 

Similar to the penis tuck. The swift tuck you do with your left (or non-dominant hand, leaving dominant hand to shake hands) when you're in public, standing up and have a visible erection.

Typically, thumb (under clothes) at the base of the erect penis and fingers at the head of the penis (over clothes). Then, push wrist down and fingers up. This results in the penis being tucked under the elastic strap of briefs or any such equivalent.

When done in one swift movement (that takes years to master) it appears that you are simply adjusting your pants/getting comfortable/scratching. This can be embarrassing but is better than the visibly erect alternative.

Co-worker: "Have you seen the bosses new secretary? She's fucking hot."

Me: "Yeah. When bossman went to introduce us I got so hard I had to perform the one-hand tuck."
