In this sense, "USC'd" focuses more on a team / group pummeling, as opposed to the individual focus of "Maualuga'd" - which has evolved from referring to damaged frat member noses to supine opposing quarterbacks. +
Ladies and gentlemen, I am giddy at the prospect of using the neologism "USC'd" to indicate a beating of epic proportions. I plan to start using it at every opportunity... e.g., "Sure the Germans and Japanese started strong in WWII, but they were USC'd in the end," or, "Back in the day, VHS USC'd Beta++"
Obviously this should be used either for beatings which had a net positive (e.g., the end of Nazism and the Asian Greater Co-prosperity Sphere) or for ironic purposes. Use of the word in reference to bad beatings, such as police brutality, is less desirable.
+ Prompt recovery from being Maualuga'd is referred to as "Cowan-ing."
++ For any youngsters reading, this is a reference to competing formats of magnetic tape used to record analog video images for subsequent viewing during the 1980s and early 1990s. Linear access and the inability to record multiple data streams in parallel were common to both formats.
