I swear to fuck
A loud promise used when someone is about to punch a pestering buddy or give a tiny kid a face full of elbow.
I swear to fuck if this kid says one more stupid joke I'm gonna stuff his face with pizza.
I swear to fuck if my friend doesn't shut up I'll throw him out the window.
I swear to fuck if this kid doesn't stop crying I'll give him a karate chop.
