How can someone "own" you?

[Logic1]

You're both wrong; it's "pwn."

Now that I think of it, does that make getting it on with a submissive "scoring some pwn-tang?"

that is the correct way yes but some other words are spelled with numbers like
l33t or 1337 for elite or yeah elite. You can pretty much say that you 1337 somebody which means you pwn them
nerd in me is on the loose http://www.dyotron.net/leetdoll/ the l33t doll hahaha

as for the own somebody part.. yes you can but not in a legally binding way though even though there are contracts for ut. You let somebody own you and control you though.
