Sinvitation 

The invitation to go against what one knows to be good and true.

He found it difficult to refuse the sinvitation to the party.

A Shitvitation is when you are invited to a friend's place and you take a massive shit in their bathroom and then proceed to leave immediately after.

Dude came over and used my bathroom like I gave him a Shitvitation.
