Interphonal relationship

When two partners in a relationship have different brands of phones.

My wife has a Galaxy and I have an iPhone. It's an interphonal relationship, but we make it work.

Clit for brains

When a woman is lead around by sex and lets her pussy do the thinking.

My niece is a reasonably intelligent girl. But since she hooked up with this loser she sure is a clit for brains.
