Disgusting. And how the hell can 2/3 of a stick of butter be healthy in any situation?

Shrink your waistline and your lifespan.

Yak butter coffee is one of the few foods named for the effect it produces on most people ....

I have a buddy who used to drop butter in his coffee at the end of a night out drinking. Actually pretty darn good as it gets you the late night fat and salt infusion you need to settle down after a night out. . . at least before the waitress brings out your meal.

Well it depends on what kind of butter you use. Fresh butter is made by whipping cream until it solidifies. So it's no different than that whipped cream in your mocha.
