I Swear To F*ck
You say it when you're so angry you're thinking about setting your math homework on fire. You pick 'F*ck' instead of 'God' because you're not just mad, you're a walking explosion.
I swear to f*ck I'll tell the principal about that detention.
I swear to f*ck I'll eat your burger if you don’t stop talking.
I swear to f*ck I'll give you the worst report card ever if you don’t stop texting me.
