Mushy-Poops

The epitome of disgustingly saccharine-sweet cutesy names lovers give to one another as a pet name and term of endearment.

1. A name given to the partner of a relationship by the other partner specifically to drive them nuts because there is nothing cornier to call them and they intend to annoy the person.

Partner 1: "Oh Mushy-Poops, I wuves you!"
Partner 2: "Good Lord, please stop before my brain implodes."

2. A term of endearment universally offensive to everyone but the sick people sincerely using it towards each other.

Construction worker 1: (Into cellphone) Okay, I love you too. No you're my Mushy-Poops. No you're MY Mushy-Poops.
Construction workers nearby: (Grab jackhammers and noisy tools and attempt to drown out awfulness).

3. A term used by a couple which does not regularly use pet names, as a source of comic relief, because they're bored and a little bit crazy.
