Arrow in the knee 

Based on one of the default conversations of guards in the game TES V: Skyrim.

If you talk to the guards they say "I was an adventurer like you, then I took an arrow in the knee".

And it really gets annoying after playing the game for some time.

So people started coming up with catch phrases like "I used to be <insert something OP here>, but then I took an arrow in the knee."

"I used to be a douche like you, then I took an arrow in the knee.

Kneesocks 

One of the two demon sisters who are the primary antagonists in Gainax's new anime Panty and Stocking with Garterbelt.

She is fairly conservative in her attire, though both the sisters wear brown uniforms. She refers to her sister, Scanty, as "Onee-sama" or "Onee-san" translated as "Dear Sister" while Scanty always refers to her as "Kneesocks-san" (Ms. Kneesocks)

While she is usually calm, she can fly into rage that causes her to turn bright red. When informed of this she claims that she "blushes easily" and returns to her normal demeanor.

Like her sister, she has a preoccupation with rules (said in the anime as "rrrurrrus", becoming a recurring joke among fans)

Scanty: Scanty!
Kneesocks: And her sister, Kneesocks!

one knee pee 

n. stance taken to effectively relieve yourself, usually during an intoxicated state, in extremely crowded areas, i.e. concerts, tailgates, wet t-shirt contests, and/or food and beer festivals (when walking to the restroom is just not an option)

pee, urinate

You are at a crowded concert and the headlining act has just taken the stage. Suddenly, the urge to pee hits you! Everyone knows the lines are long in the bathroom and it will take forever. The only other option is the one knee pee. You assume the one knee stance, pull up your pants/shorts leg past the knee that is touching the ground, pull out tool and let it fly.
Warning: the one knee pee works best under cover of darkness and only in extremely crowded areas. The author of this message is not responsible for anyone who attempts to pee uphill or into the wind.
