Those stupid septic tanks have just re-elected George Dubya Bush! Bang goes peace! More terrorismactivities will happen now, this enacted by the yanks on Iran or Syria!
Mate, I took that septic tank from the other day out for a surf. I was hoping the sharks would rip him to pieces but it looked as though they swam away in terror. It seems not even a Great White Pointer can swallow his bullshit.
Something that looks like shit (figuratively or literally), but is actually good. Named for the Hawthorn Hawks (AFL team) whose yellow and brown uniform makes them look like a septic tank of shit and piss, yet they are awesome despite the colour of their uniform.
