High horse (or high horsing) is a running gag/joke created by the Creatures. It means a person who is full of himself, is doing better than others and/or is bragging about it.
This term was first used as part of a behind the scenes video of the making of the music video for Black Label Society's song called, "Crazy Horse." SlyFox in his video switched "crazy" to "high". The gag has then appeared in several other series like the Ex-Communicated, Monopoly Streets and Dead Island. It has been used in many cases, an example would be in the first Creature House tour when the Creatures said "that's a high horse toilet paper holder."
- They have joked like the high horse has existed as a literal object and that they are sitting on it, saying things like "I can't hear you, my high horse is too high!"
