Sir John 

What you usually call an abnormally very small penis. Normally the 'sir' is added to increase the penis's already low self esteem due to it being quite small.

Me: "Hey, Dude, how is Sir John doing? Did he enjoy last night with me?"

Dude: *Thinks: She called him Sir, so I really was mistaken when I thought it was small* "Sir John is doing GREAT, thanks."

Sir John A High 

The pinnacle of average high school education, nicotine feinds and drug use. Filled with crackheads, rednecks, middle class hockey players and shitty teachers, this high school beats the rest by its diversity of middle class white kids and a few exchange students. While on the outside of the school in the student parking lot you will find on the daily burnouts, drifting, seshing and fiends roaming around begging for nicotine.

“Yo you go to sir John a high? Yeah I do!”
“Do you have any nicotine on you? Ah you must be from sir John a”

Sir Louis John Howard 

Sir Louis John Howard was a pioneer at inserting large objects into his wide, dirty anus. Some would describe him as the 'Human Elastic Band'.

Person 1 : "Have you heard of Sir Louis John Howard?"
Person 2 : "No?"
Person 1 : "Search him up, his research into anal penetration will change the way you think of the human anatomy and physiology"
