breakfassert

Breakfassert is when your first waking meal is something super sugary like cereal, pancakes/waffles drenched in syrup, pop tarts, cake, donuts, etc. It contrasts with regular breakfast, which is supposed to be an actual, savory, filling, nutritious meal to kickstart your day.

The word is a portmanteau of breakfast and dessert. It is pronounced "brek-fuh-zert".
