Shout out; Call out

       "Shout out" and "Call out" sound alike, but they're just about the opposite of each other..  If you "shout out" to somebody, you want to recognize or acknowledge, call attention to, praise in some fashion, somebody whom you want to name; you "shout out" to them and usually in front of an audience.

       To "call out" in front of an audience or in print or electronically is to point out somebody who needs reproval and needs attention called to them because of something disturbing or not good about them.  That's "calling out" somebody.  It's really the opposite of "shouting out."
