Mouth Babies 

Babies conceived in the oral cavity during a makeout after both parties have performed oral sex on one another.

My girlfriend and I forgot to brush our teeth after 69-ing, now she's knocked up with mouth babies.

mouth-breather 

Someone incapable of breathing out their nose because their mouth is always yapping. They can often be seen in forums where they're assumed to be clever. However, assumptions usually land you in jail.

Kia salespeople=everybody at Kia, involved with Kia or even knows about Kia is a mouth-breather.
