f.i.e.t.t.s.
F. I. E. T. T. S. is like the glue that holds your brothers together when they're too lazy to clean up the mess they made.
I cleaned up the mess my brother made. He said, 'F. I. E. T. T. S. or I'll clean up the mess you make.'
My brother spilled pizza everywhere. I said, 'F. I. E. T. T. S. or you're cleaning this up.'
When my brother left a mess, I said, 'F. I. E. T. T. S. or I'll leave a mess bigger than yours.'
