Sillitarian 

The belief or use of language in using an alternate completely silly word replacement in conversation and acting totally serious. The alternate word used must sound similar to the word that would normally be used in context.

Perfect examples of "Sillitarian" are as follows;
When you want to discuss things in detail, you have to be very "pacific."
In the Summertime, I have lots of problems with my "analogies"
I have a hard time pronouncing this word because it has many "continents."

Sillatard 

Short for silly retard. Being silly happy and acting stupid at the same time.

Stacy thinks she's dancing sexy on the table top. But, with those moves, and that stupid grin, she's a real sillatard.
