Game grumps is the greatest thing ever conceived!

Nah, I don't like it.

Grumpleupagus

The term "Grumpleupagus" is a combined term, taking inspiration from Sesame Street character, Snuffleupagus, and the word "grumpy". Grumpleupagus is a noun used to describe a rather cranky being. In modern mythology, some say the grumpleupaguses used their long trunk to shoo away persons they find annoying.

Oh John, you're such a grumpleupagus. What's the problem?
