look up any word, like the eiffel tower:
similar to the rusty rose except not only is the pussy raggin, it is also dusty from a long period of abstinance, leaving the penis crusted with nasty rag blood and a layer of dust.

Darryl: it took a while but i finally got jessica to put out.
Sean: didn't you say she was on her rag this week?
Darryl: ya, i pulled a dusty rusty rose.
Sean: lol! that's nasty.
