Flashbang 

When you do everything for someone and they are blind to it and give nothing back!

e.g. You are nice to a girl and all they ask is for a nice boy but completely ignore all of your actions and words.

This girl I have been talking to for 3 months has started started talking to a new guy after I did everything for her, I think she is flashbanged.
