For any people ruled against their will for hundreds of years by a foreign crown, one can only imagine what connotations the word "Royally" might carry in the (un)faithfully adopted local lingo...
Rascals, crooks, goondas, rowdy sheeters, and politicians can certainly hoodwink the innocent masses from time to time. But only a monarchy can screw an entire nation for generations. Indeed, when it comes to getting screwed, "Royally" is one of the undisputed heavyweights of the hyperbolic kingdom in Samosaland.
When a situation is sooooo dire that an appropriate modifying adjective is required to described just HOWWW majorly buggered one is, we call on "Royally", perhaps harking back not-so-fondly to just how downtrodden our forefathers were by her majesty's heels.
Find it most commonly served ahead of the following delicacies: Jacked, Buggered, Fucked, Screwed, Mothered, and just about any other less than ideal state of being... but how it's served is just as important.
-- Roll that "R" nicely
-- Turn at least one side of lip up in a sneer, two in a grimace is better...
-- Ball up your fist in front of you, arm bent about chest high and palm downward, and shake your fist towards the person you are speaking to in smooth meaningful back and forth moouments
B: "Don't ask da!"
A: "How was the exam?"
B: "Got jacked, what else?!"
A: "How jacked?"
A: "Oh shit!"
