For the same reason you "dial" a phone number. Or apply "Ben Gay" on
sore muscles.

And maybe for the same reason a young friend tells me someone is
"sick", I say perhaps the person should go to the doctor?, then he
laughs at me because "sick" now means "cool"...

FYI - A short piece of galvanized pipe is called a "nipple". So go to
the hardware store and say you need some "dope" to apply to your
"nipple"!

I'm still trying to figure out why airplanes have "cockpits" and ships
have "poop decks"...
