look up any word, like spook:
A kid usually between the ages of 10-13 that is seriously annoying or clueless/oblivious to almost everything. A Baby Binker will try to act extremely older than they actually are.
13 y.o girl: I think it's about time I settle down into a serious relationship don't you think?
Older Sister: Absolutely not, you're a total Baby Binker!
