The feeling of overly stoned/high. (More than stoned). This was made by myself when I tried saying I was stoned but mixed it with chonged, (another word for being stoned/high) by accident. So stonched was a result of this.
When you jump someone, stone them to death, then feed their dead body to rabid cannibal midgets, then collect the midgets defication bake it into a cake and give it to that persons mother on her birthday

After a day of partying, you have at least one friend who may have just had too much fun with alcohol. As a good friend, you make sure that friend is taken care of.
If your friend does these three steps, in no particular order, then your friend has become storched.
You must have three parts to be storched: drunk to the point of forgetfulness; have a friend(s) physically get you to a safe place because you can no longer walk; and you must throw up. If all three parts align, you have officially been storched.
