potassium yttrium sulfur
More scientifically accurate, Potassium Yttrium Sulfide, this spells KYS. If somebody tells you this, they either respect you enough to shit on you or really fucking hate you.
Doctor: I think you're retarded.
Retard: What can I do doctor?
Doctor: One 10mg pill of potassium yttrium sulfur should be sufficient.
Retard: thx doc!
