A combination of shitfaced and hammered states of drunkeness. Usually followed by vomiting and waking up the next morning hating yourself.
Dude, after that third four loko last night you were shit-hammered!
So thats why i threw up this morning.
Being VERY drunk
"I was so shit-hammered lastnight i dont remember a thing"
"I cant wait to get Shit-hammered tonight"
