Sleeprivationhigh
A.K.A the 3 in the morning effect. When you seem to be high off of sleep deprivation. The feeling when you're so tired that you laugh at everything even if it's only remotely funny. The name "Sleeprivationhigh" comes from the meaning getting high off of sleep deprivation.
Guy 1: Man I had a huge sleeprivationhigh last night. I even laughed at all the jokes Dane Cook made.
