f.i.e.t.t.s.
F. I. E. T. T. S. means friendship is the only thing that keeps you from getting stabbed in the back by your so-called brothers.
My brother tried to steal my pizza. I said, 'F. I. E. T. T. S. or die.' He ate the whole thing.
At the party, I had to save my brother from getting kicked out. I said, 'F. I. E. T. T. S. or I'll kick your ass out.'
When my brother betrayed me, I said, 'You forgot F. I. E. T. T. S. and now you're dead to me.'
