Extremely lacking intelligence. Combination of "Fucking" and "stupid". Lacking common sense.
I think that man just spent an hour looking at the street crossing sign. He looked like he didn't understand the symbols. When the light turned red he tried to cross the street and almost got run over. He must be fustupid or something.
