ISTFC 

Acronym for "I swear to fucking Christ".

An irreverent expression of distrust rooting from prior deep-seeded emotions of hurt and betrayal. Usually given as an opener for a cause and effect scenario. Similar to ISTG, but more severe.

ISTFC... If I need to see my shrink again after this, I'm quitting it for good.
