So my roommate has a guest over, and they asked me:
Are you a Co… …poster?
The Eggbug mug works.
If I ever talk about Cohost in real life, I promise to you all that I will use the term "chost", that I will articulate the sounds with my vocal chords, and that nothing, nor the fires of hell or the thunder of heaven, will make me stop. As a bonus, I promise to change the way I pronounce it from conversation to conversation.
/tʃoʊst/
/xost/
/kəʊst/
/ʃɔs/
