Arrow to the Knee 

In Nordic/Scandinavian countries, "taking an arrow to the knee" meant that you are getting married/already got married. It refers to when we propose, we fall to one knee, comparing it to when a man gets shot in the leg, he, of course, falls to one knee.

Like most definitions already posted the most popular example comes from Skyrim: "I used to be an adventurer like you, but then I took an arrow to the knee". The guards are married, and can't go out adventurer, not crippled.

Knee-pussy 

The spot on the back of your leg where the knee bends. When bent, it stands as an acceptable substitute for an actual vagina.

I didn't get laid tonight, so when I got home I fucked my passed-out roommate's knee-pussy.
