posting my omegaverse headcanons that i use for... every omegaverse worldbuilding thing that's still in my drafts lmao
so instead of having two chromosomes, omegaverse has 4. the "x" and the "b" are base from whoever is giving birth and then the additional "x/y" or "a/b/o" are from whoever is cumming
xxba: female alpha (estrus cycle, has a clit that hardens and grows as a dick with a knot. testicles are inside the body instead of fallopian tubes. can get pregnant and impregnate)
xyba: male alpha (estrus cycle, has an outer dick and testicles on the outside with a knot)
xxbb: female beta (no cycle experienced, has a vagina but does not slick)
xybb: male beta (no cycle experienced, has an outer dick and testicles but no knot and no cloaca)
xxbo: female omega (estrus cycle, has a vagina, produces slick from ass & vagina, can get pregnant via vagina but no cloaca womb)
xybo: male omega (estrus cycle, has outer dick and testicles but no knot, produces slick from ass with cloaca style ass-womb. can get pregnant and impregnate)
in omegaverse, people can transition gender and their secondary sex. studding turns someone to an alpha, bitching turns someone to an omega and then for betas it depends on the world. in one where they are the dominate group, turning someone to a beta is called "normalizing" but in a world where they are not the dominate group, it's called "neutering."
this whole list was inspired because a friend said they wished there were good slurs for betas and then i spent two hours going overboard because uh. that is apparently how i do things lol. some of these are also sixteenth century insults which have a star by them.
knothead (a classic, i've seen this one everywhere i think)
lollicock: an alpha with a small penis/knot
frailmate (similar equivalents could be “lacemate” in that the bond is fragile/weak, but used more so as a reclamation of frailmate)
hobby jockey (in tandem with hobby horse)
knotbreaker: omega who has shared every heat with an alpha and still not been mated
tamer: a mate-marked omega who is the younger/less-experienced in a relationship
slick-licker, for a beta/omega or omega/omega relationship
knot-pumper, for a beta/alpha or alpha/alpha relationship
matchlock: a person who tries to trigger another’s heat/rut prematurely
fuzz fervored: a person who gets passed around by a group of omegas in heat
heat seeking missile: a person who seeks out omegas in heat
rut gutter: a person who gets passed around by a group of alphas in rut
rut runner: a person who seeks out alphas in rut
sire sucker: a person who goes after dilfs
dam delver: a person who goes after milfs
mate marker: a person who leaves a mated mark on their sexual partner w/o previous discussion, usually from a one night stand
beta bitch: at an alpha in a beta/alpha relationship
beta meat: at an omega in a beta/omega relationship
patchfaker: someone who hides their scent with patches, or pretends they have a scent to hide
scent stick: someone who wears the scents of multiple partners
studder: an omega who keeps turning other sexes into alphas whether intentionally or not
like with personality types (meyers-briggs, etc), zodiacs, and blood types, there's a pretty common belief that the base of the scent you have says things about who you are as a person and your compatibility with others.
clean/earthy/green bases: someone of a reliable character. they can be perceived as uptight, but that's only if things aren't going according to their painstakingly crafted plans. they're rigidness doesn't mean they're any less creative, often finding artforms the one place they can let go.
floral/fruity/tropical bases: someone impulsive and passionate, who can find the good in any situation even to their own detriment. known for being fun-loving and quick to boredom.
lactonic/vanillic/gourmand bases: someone calm and soothing, someone who seems like they'll be little more than the girl next door, yet they have a quiet confidence.
spicy/smoky/woody bases: someone powerful who has no issue making their presence know. someone who is intimidating and standoffish at first glance but as you get to know them, their complex way of caring will show through - a wildfire that becomes a candle if you will
aquatic/musk/ambery bases: like the above scent, someone powerful. they can be gentle and playful as a creek but cross a line and their rage matches the tidal swells of the storming ocean. natural born leaders who can bring people together just as easily as they can tear them apart.
