My other boyfriend

When he has short hair, I call him My Short Haired Boyfriend, when he has grown it long, I call him My Long Haired Boyfriend, and I always implicate that I have another boyfriend with the opposite length hair. He does the same to me, replacing boy with girl.

It comes from the first time I got my hair cut after we started dating. It went from pretty long to fairly short. I didn't tell him I was getting the cut and asked him to meet me at a restaurant. When he came in, I greeted him with my short hair and he said "Wow! It's like I'm dating a whole other chick!"
