No, you haven't wandered into a Firefly revival, that's just one of the nonsensical phrases your Guild Wars character will spout while under the influence of pirate grog. If you're (un)lucky enough to have post-processing effects turned on, you'll get an eye-spraining visual effect too, as seen above.
So where do you find this wonderful stuff? Luckily for you, ArenaNet is about to kick off its annual Talk Like a Pirate event and acquiring grog is as easy as killing a level two grawl. PvE enemies throughout the world will be dropping grog beginning at noon PDT Friday, and you'll find that the NPCs in Lion's Arch and Kamadan are joining the festivities as well. They've got a swashbuckling new look, and if you take a moment to chat with them, you'll find some interesting dialogue as well.
If you need a place to store all the extra grog, ArenaNet's got you covered. A surprise update today introduced a sale in the NCsoft store, and extra Xunlai storage tabs are now half-price. The tabs are marked at $4.99 rather than their usual $9.99, and it's listed as a limited-time offer, so hurry and get your grog storage tab!
The Talk Like a Pirate event lasts through Tuesday the 21st, and the storage pane sale ends the 19th.
