This word is the result of two amazingpeople who were so happy about their friendship they couldn't control their excitement.
The word is mainly used after a few alcoholic beverages have been consumed, and is the easiest answer to most questions. Or when there is just no other word to describe the situation.
The word is never taken as seriously unless the "Foshotally dance" is used. This dance was invented by the sexiest ginger kid in town.
"Foshodo" is a lengthening of the word "fosho" and can even be shortened to "shodo". It simply means yes and can be used in any context where "fosho" fits.
