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.

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?"

1. When a girl initiates a DTR in the middle of a make-out sesh

2. When someone or something lame interrupts an otherwise enjoyable experience
1. "So, yeah, we were kissing, but then I stopped and said, 'Do you even like me? What does this mean?'"

"You said that? What a bonerkill."

2. "There was good dance music on! Who changed it and put on country? Bonerkill."

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…
