Concatenation of slacker and bitch. A slackbitch is a person (generally female, but may be male) who is extremely lazy and prone to procrastination. The term is used as a playful, mocking insult, and is most often applied to oneself, not other people. Slackbitches are usually quite proud of being slackbitches.
I am such a slackbitch, I don't use hangers or drawers to hold my clothes, they just lie about on the floor in varying states of cleanliness.
To move or pass at high speed. Can be used for a physical object ("She fwooshed past me on her bike.") or a concept ("The point of the lecture fwooshed right past me.") Often used as a sound effect for passing at high speed. Related to whoosh.
I tried to catch the bee, but it went "Fwoosh!" right past my head and out the window.
