Schubertism 

To do something with a complete disregard for others, in a stupid or sometimes funny manner, usually involves lying.

To tell a lie about something that wouldn't seem important so it is perceived to be truth by the person to whom the lie is told.

"Did you hear that lie that he just told?"
"Yeah, it's a schubertism"

Schumerism

The act of using another person's previously performed comedy material and passing it off as one's own. Originating from alleged comedienne Amy Schumer, who been documented on at least five different occasions performing jokes or sketches previously done by others.

Dane Cook just told a joke about giving somebody the bird that I could've sworn Jerry Seinfeld did years earlier...classic schumerism.

Carlos Mencia just schumerized another comedian.
