I have a few in mind as a paladin!
Glyph of the Ascended
During the duration of Avengers Wrath you will levitate as well as make your wings flap. Works with Glyph of Winged Vengeance.
Glyph of Clumsiness
You find that during the duration of Divine Shield, you trip over yourself and roll around in your bubble when you move. (think of the same rolling as the quest Roll Club: Serpent's Spine in the Vale).
For Warlock I have one
Glyph of Demonic Tongue
Teaches you how to speak and understand the demonic language.
