There can be some actions that can be pretty dumb. Just like the girl in this ad.
If there is one word that can be used for this, then it surely must be Stupid.
And what more can we learn from this stupid action?
The word we learn is ‘VACUOUS’. Vacuous means ‘EMPTY’ and by extension, ‘EMPTY HEADED’.
We can easily say it mplies being ‘emptier than a banker’s heart’ (the idiom means completely empty).
