coveter

a person who sets out to date your boy/girlfriend while you are still dating them. The situation usually ends up with the boy/girlfriend breaking up with their significant other, causing them to become a crying, worthless heap of human life. Once the said covetee hooks up with the coveter just once, they are then, in turn, broken up with, leaving them just like their worthless ex-boy/girlfriend.

That guy is such a coveter. He has to know that Wendy is still dating the butcher.

Coxster 

Older-aged men unable to afford a true exotic, buying into the Sub-$10,000 Porsche Boxster.

Often divorced and trying to have stable relationships, this great insecurity causes delusion. They will tell you their Boxster is a Carrera GT.

Honey, why is the man next to us staring?

He's a Coxster, he thinks you're impressed with his dropped top and 0-60 time slower than a Hyundai Genesis.
