Afterburn 

When playing either "Apples to Apples" or "Cards Against Humanity," it is the feeling of massive regret you feel immediately after drawing a new card when you are stuck having played a previous answer that does not work nearly as well as the new one would have.

*player picks up new card from the deck and looks at it*

Player 1: Aw, man! This would have been way funnier than the one I put down.
Player 2: That's afterburn for you.

Person 2: Why would you even try backstabbing a pyro?
Person 1: He was oblivious of my presence!

morning afterburn 

The painful but somewhat stimulating anal sensation you experience the morning after eating too many of the hottest buffalo wings the bar offers (e.g., BWW's Blazers). Some Indian food can have the same effect but usually it is only from some very irresponsible sadistic joker.

Steve: "Try these wings, they burn more coming out than going in."
Joe: "meh, they're not so bad but I can tell from the smell that they prolly are morning afterburners."

KFC afterburn 

When your anus feels like an erupting vulcano the day after you ate spicy KFC

The KFC afterburn is hitting me hard today. I don't think I can go to school with a fiery anus like this.
