BDSM capitalization is also sometimes called Slavese or Slave-Pidgin.
More About BDSM Capitalization
Some sources believe that BDSM capitalization came into practice with Old Guard Leather guidelines which insisted submissives use only the third-person to refer to themselves. Another theory is that the practice sprung from chatrooms where the capitalization helped convey participants’ roles to the online community.
Fans of BDSM capitalization feel that the practice shows respect for the dominant partner and that it reinforces the roles in BDSM relationships. However, BDSM capitalization has come under fire from some members of the BDSM community who feel that the rules of standard English grammar should always apply. They argue that respect for individuals, or the BDSM community as a whole, is about more than the capitalization of letters or the ability to use a shift key. In addition, they feel that any dom/sub relationship should be strong enough that it doesn’t need to flout existing grammar conventions to strengthen it.
