I don't think it's offensive or used with those meanings, they seem overly exaggerated. More like used as an annoying call out? Idk, like when some people go "your oppas do x and x" they say "your girlies do x and x" (obviously using oppa has its own issues, but I think its the same vibe), kinda like calling someone "sweetie" etc
Edit: my bad I thought the meanings were saying girlies meant girls that show skin lol I think the meanings are spot on but it's not offensive. It also depends on who is saying too.
