Four Banger 

The Four Banger is a booster pedal for electric guitar. The pedal contains four different booster circuits that each have their own separate boost volume knobs and their own on/off switch; this enables more than one boost to be used simultaneously. The different boosters are as follows: a Germanium Treble boost in the style of the classic Rangemaster, a super-clean Opamp boost (original design), a MOSFET boost (in the style of a certain popular boost with gain control that crackles), and a JFET mu-amp boost based on the popular DIY MiniBooster designed by Jack Orman. They are stacked in series, which enables different combinations of overdrive and fuzz.

I absolutely ripped @$$ last night at that gig, especially when I plugged in my trusty old four banger.

four banger fart/dump

Whenever you take a dump and you poop along with make a fart noise that is a result of air in the stomach, possibly heartburn. This fart will last more than ten seconds and is rather loud for a fart. It will sound like a 4 cylinder car shifting gears in fart form. It is possible that you can poop loosely too.

A four banger fart/dump sounds like a four cylinder car shifting gears and is very similar to shotgun pooping, but you do not feel a rush to go to the toilet. This poop will sometimes come out with force. The farting/poop sounds are more of an explaination for this. Four banger/fart dump, shotgun poop ( if there is a pause between the rushed dump as in diaherrea.

four bagger 

describes a woman so utterly and completely repulsive that you should be ashamed of yourself for even thinking about having sex with her.

One bag over her head.
Second bag over yours.
Third bag over the dog's head so it doesn't howl.
Fourth bag by the door in case anyone barges in.

"Cher is a four bagger."
'Paper or plastic'
"Plastic so I can suffocate afterwards"
