asspirin 

A special form of acetylsalicylic acid that you ingest to help reduce aches caused by the a**holes in your life, and/or to help you to better deal with anyone who is a royal pain-in-the-a**.

I wonder if asspirin could also help relieve the smarting pains of humiliation you'd feel if you'd unwittingly made a total jacka** of yourself in public???
