Literally "one who stuffs". Originally referred to longshoremen or cargo workers in the maritime industry since before the industrial revolution. Nowadays in common usage it describes someone who swears profusely or who garners a lot of poon tang.

In downtown baltimore, a missile is most commonly an awesome bag of raw heroin. If it's of a good quality and there's a good amount, then it's a missile. This term is also used to refer to other drugs, but mainly heroin. In the last year or so it has seen repeated use as a replacement for "the bomb". In this context it can be used to describe anything of an exceedingly high quality.
I once was buying a bag of weed and had it broken down for me by a native. I commented the bag was a bit small, and he replied to me, and I quote:
"don't even worry about the size, baby, it's a <i>missile</i>"
I asked him what that meant and he told me it was like the bomb, except it gets shot straight into your nose/lungs/veins.
A nuclear missile is better than a regular missile.
That dope I got from Jimmy The Hat was a fucking missile, I shot up yesterday and I'm still fucking wasted!
