A Soda Yoda is a soda whose drinker talks like the Star Wars character Yoda the whole time he drinks the soda. For example, instead of saying "this soda is yummy," a Soda Yoda would say, "yummy this soda is."
"That guy talks funny and he's got a cup in his hand--must be a Soda Yoda!" "Finish this soda, I must, for a Soda Yoda, I am."
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
