Shady's Back

Refers to Eminem's intro to a few of his songs, notably Without Me from The Eminem Show.

Guess who's back
Back again
Shady's back
Tell a friend
Guess who's back,
Guess who's back,
Guess who's back,
Guess who's back...

Back EMF

The counter-electromotive force (abbreviated counter emf, or CEMF ) 1 is the voltage, or electromotive force, that pushes against the current which induces it, is caused by a changing electromagnetic field. It's represented by Lenz's Law of electromagnetism. Back electromotive force is a voltage that occurs in electric motors where there is relative motion between the armature of the motor and the external magnetic field. Counter emf is a voltage developed in an inductor network by a pulsating current or an alternating current. 2 The voltage's polarity is at every moment the reverse of the input voltage 3 4

In a generator using a rotating armature and, in the presence of a magnetic flux, the conductors cut the magnetic field lines as they rotate. The changing field strength produces a voltage in the coil; the motor is acting like a generator.. (Faraday's law of induction.) This voltage opposes the original applied voltage; therefore, it is called "counter-electromotive force". (by Lenz's law.) With a lower overall voltage across the armature, the current flowing into the motor coils is reduced. 5

Pretty self explanatory dont you think, i added this as the previous entry was rubbish and he's obviously visited an engineer who doesn't know what back EMF is.

Bitch Back

Reclaiming your crown.

Speaking your truth and owning it.

Being confident and holding your boundaries.

Got your groove back.
Stepping into your power.
Bad Ass!
OWN IT

"No one's messing with you, you spoke your truth you got your Bitch Back."
"Girl fuck that, get your Bitch Back."

Back to school

The phrase you dread seeing most in the summer holidays when you go into town for uniform shopping. Why on earth should stores torture you with a reminder that schools just a few weeks away?

I went into Pound Stretcher and saw what i dreaded most, signs saying 'Back to School'.

Skunk back

Send the skunk back to the woods!

Get the toxic person out of your life or place!

He cheated again, just send the skunk back to the woods!

hammock back

When the pattern of a hammock is indented into your back.

I passed out on the hammock for 12 hours and had a bad case of hammock back when I awoke.
