Trippopotamus 

A hippopotamus that is tripping on psychadelic drugs such as LSD or Pscillocibin mushrooms. They commonly reference "trippin' balls" and "Grateful Dead laser shows".

I took mushrooms at the Bassnectar concert with a Trippopotamus that kept telling me about the Grateful Dead laser show he watched last week.
