Melancholic pondering while cleaning

Drinking Port,
drinking Port.
I'm of the sort,
That likes drinking Port.
Anyone trying to thwart
my drinking Port?
In short;
to abort
the Port?
Deport my consort?
No more cavorting
with my Porto imported?
Be damn sure,
I'll hold the fort,
snort,
and resort
to F*ing violence.
