Meh.

Meh. Meh! Why is it so fun to say meh?! My friend Ari says it all the time (quote Ari: Enguh!)
Let's just say that's a subspecies of meh. But anyway, meh is a good release word for me. There's a shirt that says meh. Meh is everywhere.

Meh. Meh, meh, meh!

If you don't know how to pronounce meh, its like "me", but with a heh sound at the end. Not "meheh", but meh.

and, of course, the famous Meep.by Beaker.
Oh, poor beaky. You always did light yourself on fire. Poor, poor beaky.
