Sack of Hammers 

Used as a degree of stupidity, it expresses one's explicit opinions of one group or individual's obvious idiocy.

1) Jane is useless, and she's as dumb as a sack of hammers.
2) Bob, I've known sacks of hammers that could toast bread, what the hell is wrong with you?

Sack of hammers 

After a long night of drinking, doing drugs and smoking the dope you feel as if you are a geriatric. Tired and unable to preform the simplest tasks. You feel... like a sack of hammers.

Holy shit man! What a night! Drinking and doing all those drugs was fun but now I feel like a sack of hammers!

knock-kneed, hammered-down, hollow-chested, smelly sack of Siberian sheep shit 

a loser or piece of shit individual; a tool or undeniable goof.

I have absolutely no respect for that knock-kneed, hammered-down, hollow-chested, smelly sack of Siberian sheep shit...what a scumbag!
