Hey there,in some anime,there's this boy who's really obsessed with his little sister and keeps mentioning her left and right,because of that,they call him sister complex;what does complex mean in this context and can you gimme a couple examples?Thanks.


Do not write "gimme", "gonna", "wanna", "lotta" or "kinda". Just take my word for it.

A complex in this context is a reference to psychoanalysis. I guess the popular complexes are the Oedipus complex and the inferiority complex. You can make up any complex you like by putting the desired noun in front of the word "complex", and that's what the anime people have done. However, the person is not the complex as your question suggests. He has the complex.
