Self referencing literary devicesThe key to this trick is to create original and indulging characters. Then you put the character two in steps of character 1. Character 2 will casually reference about character 2 in his situation. I know it sounds so bland. But here's an example:
Her boyfriend dodged every defence and was almost going to score a goal. But when he was tackled by seven people at a time, he pulled a Caeser and went down.
Here we see how character 1 is referencing Julius Caeser. Caeser was assassinated by his many conspirators. So without much description we can explain what was going on there. It doesn't mean that the boyfriend in question is dead. It just means he stood no chance against his conspirators/rivals.
Description is one of the most sought after talents in writing. But not every situation deserves a description. Sometimes referencing or self referencing can save your descriptive efforts for something bigger.
Example 2: "I cannot use this washroom. Its so ugly. I'll pull a Polnareff till I reach hotel room."
Polnareff in this said example is a French guy who doesn't like to relieve himself in dirty bathrooms. So he waits till he reaches the hotel. The other character who quoted the above sentences is saving the description by just referencing to another character.
Note: Second example here is a self referencing one. First one falls in the lines of metaphors.
