the act of pleasuring your significant other and cleaning their colon at the same time. This is usually executed using an industrial strength pipe cleaners (these can be found at your local SuperWalmart).
"Dude how come you couldn't hang out last night?"
"Man I've been gettin the poop dick from my girlfriend every time we do anal, so I had to stay at the house and give her a good chimney sweeping."
"Oh, sweet."
(not offensive to anyone whose actual profession is or was a chimney-sweep):
a) a very offensive term used by white people to insult other white people who are not only pro-miscegenation but are, regardless of actual truth, perceived to have a non-white significant other.
b) a so-so offensive term for a grease-monkey or a janitor
c) a very offensive term used by white middle class intellectuals to insult members of the white urban working class who hang out exclusively with black members of the urban working class and who become more 'black' than 'white' in terms of 'manners', music taste, etc.
if you are called a chimney-sweep, especially definitions a) and c) above you are not only pro-miscegenation, and don't really care about interracial marriages and stuff, but you have no clue what the term ehre weiBen kultur means.
When a woman inahales a large amount of smoke from a bong and holds it for a minute. Just before she exhales, you shove your dick deep into the back of her throat, blocking her airway, so she can't exhale just as if a chimney was clogged.
My gf wouldn't go past 3rd base, so I gave her a chimney clog till she passed out and made her go all the way without her knowing.
