Actually she called an action figure a doll, and I had to school her on the finer points of toy definitions:
Doll: [dol] - noun: If the removal of pants is a component of a toy's play factor, said toy is a doll: Hey Chunky B, did you see Brian's Lee Majors doll? It came with two pairs of sweat pants and one swanky leisure suit!
"Holy underwear - I don't even wear pants!"
Action Figure: [ak-shuhn fig-yer] - noun: A manly toy collected by manly toy collectors. Pants are non-removable. Often carries a weapon of some sort: Hey Bubba, your epic Batman action figure collection eclipses Reis' mere handful of Batmen, which are mostly bootlegs anyways. I'd wear a mask too if I were him!
"His Robin collection ain't nothin' to sneeze at either!"
The girlfriend then asked 'Who decided upon these definitions? Who is the authority?'
Well, moi, of course!
And now it is written, and so shall it be forevermore.
(Oh yeah, toy collectors are also a fun group of folks who can really take a joke...I hope ;) )
