Gack! That was rather horrifying. *shivers*
I don't mind a certain amount of japanese, as long as they know what they're saying, but an assortment of misused words picked up at random is just scary.
On the flip side,though, I defy anyone to name an anime that doesn't contain at least one bizarrely misused English word or phrase. I no longer lend anyone my Blue Seed collection without a warning, because the next person who asks me what exactly the phrase "pick me up foxy night game" implies is going to get the box set shoved down their throat.
