Crowded Island...

This island is packed with people,
of all shapes, colours and sizes.
You can almost kiss someone's pimple,
but be prepared for surprises.
It is way too crowded to move,
during weekends in the city.
Everyone is feeling the groove,
there is no missing actuosity.
Squeezing is an essential skill,
or one will be stuck to the ground.
Some might find it a cheap thrill,
so beware of perverts around.
You might feel frustrated,
and the urge to push develops.
When you are exasperated,
try impersonating an antelope.
Everyone is as fed up as you,
so walk slow and follow the flow.
If you step hard on someone's shoe,
apologise and just lay low.
Boarding the train you think is empty,
turns out there is a lasting party.
Mixtures of perfume and smells quite farty,
changes you green and feeling so queasy.
The kid behind you is facing your rear,
but it's less awkward than your crotch.
Just as you're deciding which way to steer,
another kid raises the embarrasment notch.
