This isn't sexist...it's a pretty common occurrence. As a man, I sit on my ass and play videogames, while my girlfriend cleans the house and yells at me for wasting my money on videogames and not helping her clean up.
While this obviously doesn't occur in 100% of households, my mother cleaning the house and yelling at my father for sitting on his ass watching TV happened a lot, and it seems to happen to my friends too. So it's clearly a common occurrence, so I don't see the sexism. All it says to me is that women take pride in their home and want money cleverly spent, and appreciate a night out every now and then, while men think of nothing more than Batman and sitting on their ass.
Wait. Who is the ad sexist towards again?
