A sexual fetish relating to being shrunk or being around a giant(ess). Macrophiliacs get a sexual thrill from the idea of being at the mercy of either a gentle or violent giantess. This fetish is linked with fetishes of being eaten, being squashed under the giantess' foot or butt, worshipping the giantess to having her go on a rampage.
Ever since John was a kid he drew pictures of giant women. Now that he is older he searches "giantess" on youtube. John has macrophilia.
