Like when your having sex and your mom calls wanting to know your sweater size.

bonerkiller

A person/thing who kills the mood when everything is going great.

Think of a situation going your way when a person just ruins it in the worst possible way. You then go, "Why do you have to be such a bonerkiller?"

toyota bonerkiller

A Toyota Prius. Well below the commuter standard of a Toyota Corolla, which is tepid in the eyes of most men. A driving experience that is the polar opposite of an unattainable and desirable car.

I see you decided to trade in the BMW M3 for a Toyota Bonerkiller. Good for you…
