A man in a red speedo confidently walks up to a bus stop, passing by several different people -- One being a gay man with a small, toy dog. Everyone looks at him strangely until he takes out some Trident Splash and pops one in his mouth. As soon as he does, a giant wave of water unexpectedly splashes over everyone at the bus stop, leaving the man in the speedo the only one dressed correctly for the occasion.
Although this ad does not single out the gay man but it does incorporate the stereotype of gay male "femininity" by showing him clutching a small dog.
