To fully understand the true meaning of Spagack, one must picture having it screamed at you by a half-crazy, teenage trailer trash guy in a violently yellow shirt from a car driving past at insane speeds, while you stand on the sidewalk and wonder what the fuck just happened.
"Oh man, I'm spagacked outta my gourd."

"SPAGACK!"

"Basically, I just want to go to this rave tonight and get totally spagacked."
