masto admin psa: if you see brazilian users posting the word "poc", it means a pejorative slur against effeminate gay men, so take that as you will
as for the etymology, as far as i've been told, it's claimed to be the onomatopoeia for the sound of high heels walking
even if the word doesn't have this exact meaning anymore, the new wave from twitter is using it to pejoratively refer to people they don't like
so the connotation is still negative and something you might not want in your instance
