Bang-Guilt 

The guilty feeling (usually awkward, depending on your morals) that occurs in the morning when you see the father of the girl you were banging all night in the next room.

When I went downstairs in the morning, I had major bang-guilt when I had to share the same coffee pot with the screamer's dad.

guilt bang 

When a person "usually a Narcissist," mentions several of your friends who supposedly also agree with them, that your behavior is not appropriate behavior. It can also be called a "guilt-pile-on."

My sister, my therapist, and my best friend all agree, . . . going to a bar to play pool without your girl friend is not okay.

I can see you are trying to "guilt bang" me with your fabricated authority figures.

Guilt Free Bang 

The act of intercourse for married couples who, because of beliefs, did not have sex prior to marriage.

Sally really wanted to get sum, but knew she would feel really bad about going against her beliefs. She found a husband as soon as she could and got her guilt free bang.
