Starving posterior

Day today whatsit

A hungry bum is never fun
On pantaloons, there's wedging
You try and remove the obstacle
without some deep down dredging

In public places full of folks
One shouldn't be that keen
You cant actually fish it out
Cos it would seem obscene

So you do walk and squeeze those cheeks
and hope no one will glance
Until you're up against a wall
And now you have your chance

But do beware! I say to you
For wedge's have a foe
Don't hoist your trouser up too high
For you'll get a camel toe
