Sometimes a cold blooded murderer

Sometimes,
Or most times,
I think of bottle openers –
The bottles they open
As women’s heads
Popped open by a head opener.
I’ve never used a bottle opener.
Instead,
I open my mouth,
Put the bottle between my canines
Split the head without any trouble.
Sometimes,
Or most times,
I think of bottles
As women. But really,
Biting them open
Seems kinder than popping them open.
Firstly, biting can be useless, sometimes –
Things can be difficult to bite.
Secondly, popping
Makes things fizz.
Well, sometimes.
