This is from my Urban Dictionary Word of The Day:
August 09: social plagiarism
When one uses a story/saying/information/
Maegan tells Leann that she talked to the band about their performance date change in Santa Cruz.
Later that evening, Leann tells a group of mutual friends that the performance date has been changed, without citing/acknowledging where she originally obtained this information. In turn, implying she spoke to the band herself, which could be construed to some as lying.
Thus, Leann commited social plagiarism.
