Yak an extremely small town in northwestern montana, complete with saloon, one-room schoolhouse, and general store(this is it's entire town). The "Yak attack" is when bored natives drive in a triangle from Yak, to a town called Libby, to another town called Eurika, and back to Yak, hitting every bar along the way.
I survived the Yak Attack, but I have a serious hang over.

6.
Slang term used for cocaine by people who are funny, awesome, sardonic, sarcastic, light-hearted, or gangrenous. Possibly derived from cocaine's tendency to make partakers particularly chatty (as in prone to "yakking) and intensely interested in speed-talking about their relationship with their mother, their thoughts on national economy, or how much money is required for the nearest large-mammaried lass to let them do a line off her boob.
"I was planning to buy a laptop with my paycheck this month because I don't have any credit history, but I bought some yak attack and ended up doing lines at a strip club all night and spending $200 for a blowjob that I couldn't get it up for instead."
