Punji Stick 

A punji stick is a weapon used in the Vietnam War. Pits would be dug filled with sticks that were rubbed with frogs poison or human feces. A soldier who fell in such punji stick pit would be have to carefully remove his leg furthur immobilizing a troop from their mission.

In the 1980s, punji sticks were carried by homeless people in NYC. They constructed punji sticks using a piece of wood with a nail driven through the tip. They would often urinate or deficate on it to cause infection on top of injury.

Yo! Step away from that bench! It's mine! You better watch it because I got a Punji Stick in my jacket!

Punji Stick 

A fetish where one's penis or strap-on induces sepsis ( or other stool-related disease ) by wantonly switching from anal to vaginal penetration .

We sepsis bonded with my punji stick last night . I really think this hospital visit will take our relationship to new heights.
