i use either abecrudele or Avery Blare as my pseudonyms.
For abecrudele, abe is my names and my middle initial together. crudele on the other hand is an Italian translation of my surname.
For Avery Blare, i picked Avery because i liked the name and because of how close i see it to abe, giving it a more gender-neutral feel. Blare was originally Blaire, another name i liked, but i did not like the whole firstname-as-a-surname thing so i looked for the closest word to Blaire. It is funny that i chose a word meaning loud when i’m rather quiet.
