okay so get this, humans like to simulate procreation with objects not intended for it, right? They do it with their digestion entry points too because it produces pre-digestive fluids that resemble the lubrication of reproduction organs to reduce friction and make it more pleasurable. One way of increasing this faux lubricant output is by inhaling air to stimulate the glands within the orifice which produces a sound which is onomatopoeically similar to the word for a predatory flying organism (hawk), while the act of ejecting the fluids creates an audible exasperation which can be phonetically reconstructed as "tuah" (IPA: [ˈtʼɤ̂ː]). The point is, it's a really lame joke and I want them to destroy us for ever making it a thing.
