ELI5: After a penalty in football or basketball, they often show the referee and coach engaged in conversation. What are they discussing since the penalty can't be reversed?

Few things: sometimes the call can be reversed. Other times the coach simply wants explanation of the call. Finally, the coach will often attempt to make a point to the refs which will help them later in the game. Example: Basketball player gets called for a charge. Coach tells the ref that the other team has been flopping and that the call shouldn't have been made. Next time a player falls down, a charge may not be called due to the coach "working" the refs.
