modorro
Refers to someone who is groggy, dazed, or slow-witted, as if they are half-asleep or not fully aware. It originates from a condition in sheep that makes them act erratically, lose their way, or fail to recognize their young (in Spain, the related noun modorra specifically refers to the heavy sleepiness felt after a meal).
You are modorro, you do not understand, you do not get it. Being amodorrado is like being dazed.
