being called doc/dokie

Meron kaming terror prof SA patho, and she called us out for calling eachother doc. Many of my peers found her to just be a killjoy, but I for one fully agree with her. It's a title we have not earned yet. Alam ko Naman na parang pang "manifest" Lang o "claim it" mentality, pero tingin ko it's disrespectful to those who actually earned the privilege to be called doc.
