Shout-out
From Wikipedia, the free encyclopedia
A shout-out is a greeting or acknowledgment of a person, group, or organization of significance. It is often done as a sign of respect, synonymous with "giving props."
The Oxford English Dictionary dates the term back to 1990, and notes that in the United States the term is particularly used among fans and performers of rap music (shout-outs are of particular significance in hip-hop culture), while in the United Kingdom, it is particularly associated with the rave and club subculture. On either side of the Atlantic the term is not limited to those groups.
