Swarmy is similar to a 5 letter word used quite commonly in the USA which starts with N, has 2 Gs in it, and ends in A, in that it is also exceptionally versatile depending upon context.
Swarmy may also be used very similarly to how the Brits use the versatile term "bloody." In fact, it may be worthwhile to research a possible morphism between the two.
"Take that swarmy bastard beneath deck! He will feel my sword for pilfering my doubloons before I keelhaul the Son of a Bisquit Eater!"
(This amounts to a death sentence.)
"Must I mop the swarmy deck again, Captain? I've mopped it twice today already!"
"That's a swarmy lot in the pub. Take heed not to cross them."
"Don't be a swarmy peg! We agreed to split the treasure 50/50."
"Is it my turn to be in the swarmy barrel already? May I pass, Mateys? My rump is still sore!"
At it's best:
"Here's a toast to the swarmiest pack of skallywags on the high seas!"
"I've a ship of swarmy men, and today is glorious!"
"There is nothing I'd not do for the swarmy pack of dogs I call my crew." *
* Notice how the manly professing of love is disguised in absurdly harsh descriptive words. Pirates never say, "Matey! I love you!" That just doesn't happen. So you must consider the context and manner of speech to interpret the meaning.
