Always watch your back

I went to see a show
Not too long ago
Had two friends performing
And I showed up without warning

All my friends were surprised
To see I had arrived
We got into the car
The bar was not too far

It was a five dollar entry
We got in, the place wasn't so empty
The show got on track
When I received an elbow to the back

I turned to see my ex
Which I really didn't expect
She seemed pretty glad
That she had got me mad

I went out for a smoke
To hope I wouldn't choke
She came out not long after
With a disgusting little laughter

I wasn't in a good mood
For she had been very rude
I confronted her with my dilemma
And hoped she wouldn't be my lemma
I said what I had to say
Then tried to walk away

She thinks that it's okay
Because I am a man
To go ahead anyway
And slap me open hand

That's what got me going
So I went to sit inside
She came to the table groaning
I just wanted to die

She was doing well abating
Saying I got these rumours exerting
Hit me here and there
Trying to give me a scare
Got up, shoved her back
Hoping she'd understand that
I did not want to be here anymore
So I went to find the door

Finding myself berserk
But I was just totally berk
Almost broke my knuckles
From all those powerful shocks
There weren't any chuckles
After beating that metal box

Neither pain nor feelings just rage
From the problems that presently engaged
All of this for what
A girl that acts like a nut
Never again will I deal
With the feelings she made me feel
