Glass? What Glass?

I'm not a 'glass half empty'
or a 'glass half full' kind of guy.
I'm more a 'glass? what glass?'
brand of arsehole.
So, if you can pour me a drink
without spilling it,
I'll tell you what I think,
for what it's worth:
There's many a shit
with a bottle to his lip
and an attitude
that's nowt to do with thirst.
I've not got water on the brain,
but a cortex on the rocks
and there's more muscle
in my mouth than in my cock.
When you see me in the bar,
you know it can't be 'happy hour'
and this weed between my teeth
sure ain't no flower.
Tell Bukowski to jerk off,
there's no more room
at this here trough
for goons who like to wallow in the gloom.
