S'd 

Short form for stoned. Potheads have created this word as they found using short forms made it easier to comunicate with one another.

"look at you man, your fucking s'd!"
"im soooo s'd right now"
"lets get some taco bell for after we get super s'd"
"black guys eyes always look like they are s'd."
