Something so throughly drenched epic sauce it surpasses sickosity and nastiness pauses briefly on sick nasty and explodes in the uncharted regions of sick double nasty. One guy said he saw something that was sick TRIPLE nasty, but we're pretty sure he made it up because that guy (Steve), (you fucker), is a dirty fucking liar who lies all the time. No you did not see Brad Pitt buying a slushie, Steve, and even if you did we wouldn't like you any more than how much we hate you stupid guts now.
Philip: Have you see Jerry Hsu's part in Back of Suck yet? Sick double nasty. No other way to describe it.

Steve: One time I met him at The Source by Circuit City when I was buying a Wii wheel with my dad!

Philip: Steve, I...you...fuck you Steve. I'm really sick of the things you say.

A slang term embraced by the young generation, "Sick Tight Nasty" or STN, has become the go-to expression for describing something super cool and impressive. This term originated from the need to convey unparalleled enthusiasm and awe in response to remarkable events, experiences, or individuals.
In my office, a phone call permeated the air. It was Matt, our resident problem-solver extraordinaire, engaging in a challenging conversation. It was a tenant who was livid about a broken blind. Their frustration echoed through the phone. Matt remained unfazed.

He effortlessly diffused their anger, replacing it with understanding and empathy. Matt's ability to relate the impact of the blind on their daily life was nothing short of remarkable. He explained his action plan, detailing how he would rectify the situation. The tenant's tone softened. I marveled at how Matt transformed their frustration into optimism. A sense of triumph radiated through the phone line. The once-irate tenant was now filled with gratitude. I couldn't contain my excitement any longer.

Me: "Yo, Matt!" I exclaimed. My voice carried through the office, turning heads in curiosity.
Me: "That was straight-up STN, my guy!" a wide grin spreading across my face. Matt chuckled, his voice filled with the nonchalant confidence of someone who had faced death, but death ran away.
Matt: "Ain't nothing but a thang!" his words resonated with a sense of humble pride.
Matt: "That's my fourth five-star review today. Stay Sick Tight Nasty, my friend!"

I couldn't help but feel inspired by his unwavering dedication and exceptional customer service. I realized Matt's actions were more than a job requirement—they were a testament to his character and ability to make a lasting impact on the lives of those he STNd.
