The state of mind in which a person, who due to lack of sleep, appears to have become heavily intoxicated. Often associated with inability to move body parts, laughing maniacally at idiotically simple actions or objects, incredible randomness, and revealing secrets that normally would not be brought up in conversation. Often for good reason.
Ted, in this situation, is experiencing sleepdrunk of the fourth degree.(1-5)

Get the sleepdrunk mug.
being in a state, where you are so tired, you start behaving as though you are drunk; eg. talking nonsense, unstable walk, forgetfulness, etc.
I am sorry, I just can’t think straight right now; I am so sleepdrunk.
