When you loose a hard-on

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…

Pontiac Bonerville

Obviously it's a play on the name of a famous muscle car (the Pontiac Bonneville) though it refers to neither muscle nor car, but a very stiff erection that steers its owner wherever it wants to go (to a nice warm parking garage of course).

He was driving his Pontiac Bonerville around the house again.

Bonerkill 

The complete and utter eradication of any positive sexual feelings present in a male's erect penis, rendering it flaccid.

Not to be confused with "Buzz-Kill"

Immediately after the intro of the Victoria Secret Fashion Show featuring Marisa Miller, Alessandra Ambrosio, Heidi Klum and other thorough-bred dime pieces in hardly any clothing, a commercial of an overweight Elvis is aired. Ew...Bonerkill.
