The gluttons dig their own graves with their teeth.

Gluttony (noun) : The habit of eating too much.

Also means, over indulgence or over consumption of food, drink, wealthy items or anything else that gives pleasure.

Of seven thrones and seven kings,
Each bearing the price of a sin
There's one piteous to me
It's none other than voracity

He's overt the best of the best
Everyday's a fest, and people are zest
With a forced smile he always lied
And no one saw he was dying inside

Women and power and gold
At the expense of a cost twofold
Whilst more and more filled his cart
The void grew bigger in his heart

An insatiable thirst of profuse
A ravening hunger for twos
He's victim of such deplore
Gluttony's his name of abhor
