Jail 

Context:

My informant first heard this saying on social media when she was in high school. She either will simply state “jail” or say that someone “deserves jail” for something that they either said or did. It is often used when people say something unexpected, strange, offensive, etc. 

Analysis:

This slang word or term is used in casual conversation to convey a form of shock or disbelief, most likely used around friends. It builds on the sentiment that someone said something or did something that was so unbelievable that they deserve to spend time in jail as a result of their actions. The use of this phrase would only make sense in a culture where there is a criminal justice system and amongst people who are often on social media sites where phrases like this are often used.
