L.Y.B.B.
L. Y. B. B. is when you were so broke last year you could barely afford to buy your own lunch let alone a snack.
'L. Y. B. B. I had to eat cereal for breakfast and hope I didn't get a stomach ache.'
'L. Y. B. B. I had to wear my brother's old pants because mine were holes.'
'L. Y. B. B. I had to skip the bus and walk 2 miles just to save a few bucks.'
