Is it bad being called a baby bat?

well for everyone my grade and lower i got the reputation of "emo"/"hardcore rocker" bleh. but anyway, ive recently started hanging out with older kids, 2yrs to be exact and when we were talking about music one of them started labeling us for fun. she said being that i am the youngest I was the baby bat. i've heard that it usually means a wannabe/poser/youngster just going through a goth phrase. but we are not goths. we just like rock. stupid question, but i just want opinions, what do you think she ment?
