When you get extremely excited for an event you are looking forward to as an adult, and your body tenses up to the point where you can't talk or move correctly.
As we sat and planned for the party at the lake with my friends, I got the greechies and couldn't talk or move for a few seconds.
Griechenland syndrome
You haven't had your retardation dignosed (yet) but you say random things just for fun even tho it ain't one. Your random statements may include irreverent jokes or words in foreign languages. This whole phenomenon happens out of sudden compulsions that make you say that without even realising. Don't confuse with tourette's syndrome as these compulsions can be fought and you may eventually recover from this ilness. Can also occur in text messaging.
Griechenland syndrome:
EX 1:
Subject 1: "hey there, remember not to cum in the rum"
Subject 2: "Cockram what"
