If a man came up and asked whether he could motorboat* your breasts, you'd be well within your rights to give the creep a slap.
But if said creepy man was donating $20 (£12.35) per motorboat to a breast cancer charity, does the rating on the misogyn-o-meter go down?
It appears, for many, it does.
At the time of writing, the YouTube video has racked up more than 3.6 million views - 44,877 of viewers have 'liked' the video, while only 1,258 have given it the thumbs down.
The men, from Simple Pick-Up, thrust their slobbery lips between more than 100 women's breasts. In total they donated $2080.
We remain unconvinced. Exploiting women's - or indeed anyone's - philanthropic nature in this way is well... exploitative. And misogynist. And creepy.
