A woman who, not unlike an
M-80 firecracker that one might buy under-the-counter from a Chinatown store, explodes with loud noises during orgasm. Typically used in the context of a woman for whom such a response might be unexpected, either from the sex leading up to it or her outwardly
prudish demeanour.
Friend: You
wanna bone Caroline?
WTF dude... not only is she a Bible Studies leader, she also wears a
purity ring.
Me: Yeah, and I bet she's a total firecracker.
