Flashbang

Noun.

The act in which a female gets a light bulb shoved into her baby maker by someone else (glass end first), and then that person proceeds to give the daring, brave and very stupid female partner a swift punch to the lower gut, thus popping the light bulb. Named crudely after the flashbangs used by law authority that pop and disoriented with a bright flash of light.

She said she wanted to try something new in bed, so I gave her a flashbang.
