Warning: Using the word "very" more than three times in a sentence is punishable by a 30-second penalty.
This sentence, for example, is a prime example of the offense: "This cake is very, very, VERY good!"
Using colloquial expressions, such as "gonna" or "wanna," in writing is a serious offense and will incur a penalty.
This sentence, on the other hand, is a classic example of the offense: "I'm gonna head to the store, and I'm gonna grab a sandwich."
