The whole Diet Coke Break advertising campaign is premised on groups of women "acting this way".
No, it isn't. That campaign works off an ironic reversal of the usual scenario of male labourers/road workers/windowcleaners shouting 'look at the tits on that!' at a random woman passing by, minding her own business and getting aggressive if she doesn't respond. But in fact it alters the parameters/power relationships considerably to make it more acceptable and less challenging - a realer scenario would have had a bunch of ungroomed, conventionally unattractive women, including older women (no make up, body and/or facial hair in evidence, saggy breasts and ass cracks on unashamed show) roaring 'I'd fuck you into the ground!' at an obviously nervous young, good-looking man, and getting nasty if he doesn't respond.
Whereas the two Diet Coke break ads I can think of suggest the man being watched/lusted after is still the powerful one, not some kind of passive object - he takes off his shirt in a public place, he drinks unselfconsciously, and in the park one, he takes the attention as his due and walks off in command of the situation.
The ordinary-looking female office workers in the older ad are safely behind glass and not able to infringe on the builder's life at all, and the suggestion is that they're sad frumps getting a bit of vicarious thrill in a dull day.
The later one with the picnicking women in the park and the gardener is even more prettied-up and 'safe'. The women are all young and gorgeous - like a Benetton ad, one gorgeous brunette, one gorgeous blonde, one gorgeous redhead, one gorgeous black woman - and the gardener is perfectly happy with their flirtatious approach takes back control by doing a striptease, and making them a passive audience before he walks off having 'won', while the watching women are left open-mouthed.
Basically the park one is a male fantasy of what it would be like to have the body of a Greek God and be leered at by a bunch of supermodels.
And let's not forget this is to advertise a calorie- free product aimed at women. The ungroomed catcalling 'male' women in the 'realer' reversal scenario wouldn't be drinking Diet Coke because they wouldn't be worrying about their weight.
