chngjn and hyvnbn are the ones i see most often!! as for individual names, i always see chngbn/bimie/cb/scb (sometimes chngb!n or b!n) and hynjn/hyvnjn/hyvn/hj/hyj/hhj (sometimes hynj!n, hyvni or hyvne). for emojis, bimie has dwækki variations 🐷🐇, 🐷🐰, etc and some people (like me) use 🦁. hyvn has 🥟 (and veeeeery rarely people still use 🦙). that's all!
