An H.N.B. is a hot new boyfriend. This is for all the ladies who go through boy friends like pieces of candy ;). An HNB is a significant other that you text 24/7, joke around with, and give a peck to once in a while. All your friends envy you because you always have an HNB. This boyfriend is just too hot to describe that only staring at his face and calling him HNB will justify his hotness.
Kassy: Too hot. I am burning up just by talking about my HNB.
Santy: I wish I had an HNB!
Kassy: Yeah, well your not getting mine!
