In the youtube video called "smoking" by the comediankyle mooney, he references a drug such as purp scurp in such a way that makes fun of all the drugs, especially weed, that people do.
"Derd, take out some purp scurp so we can get super sconed"
Means literally anything you want it to mean. Ambiguous but nonetheless, the skerpiest word of all time. Commonly also used as skerpy derpy, skerpiest, mmmm
