My son also uses it frequently, he learnt that word from a Captain Underpants book or one of the other works from dav pilkey so maybe its from there

Yes but thru your mouth

Anything from golden age Cartoon Network (dexter, coward the dog etc)

My two kids have dual nationalities (korean and another). The oldest the korean consulate in my home country for reasons we never understood they registered his name <Surname> <Middle Name> <First Name> on his passport. So when filling forms, buying tickets etc using his korean ID his given/first names is actually his middle name. This has caused a lot of problems, specially when compared side by side both of his IDs.

For the youngest one we filled the paperwork following the same pattern of the oldest, which the korean consulate guys said was correct. However, when his passport arrived his name was <Surname> <First> <Middle>… for which the consulate workers just scratched their heads and said uhh yeah anyways…

Edit: another example to follow OPs topic, my wife is korean and her passports list her name in both Hangul (korean) and Roman alphabet. Korean with Last/First + “Middle” and Roman as first + middle + last. Her IDs abroad use the roman name.
