The state of being so tired that you act drunk or hammered. May cause one to ramble about irrelevant topics, slur words, and lose all focus. See also "Drunk-tired."
Person A: Were you drunk last night when you were talking about hedgehogs?
Person B: No, I was just tammered from pulling an all-nighter. And hedgehogs are sweet.
To be drunk enough that tanked or hammered does not describe the drunken state you are in, you have to combine the two words.
Eddie: I was so tammered I shit on a wall while I was vomiting.
